      And in the gui under system CPU usage shows as 100% to the wall, but when I turn off captive protal the problem goes away.

        Wait until it happens again then get a top reading.  This reading shows nothing wrong:

        60.5% idle

          Still hasn't crashed since the last post, there are often 10-15 users hitting it though, and I do have an ip address on the pass through ip in both directions, it is so they can follow a link to a sign up page where there information is entered and checked against a master database.    I don't know that th I'm running top right now though, I'll give you the reading when it crashes again

            This is the latest, this time it didnt' kill my ssh session, but it won't respond to additionall ssh or web gui requests, it looks like something is causing the swap partition to overflow, 856M used isn't what I would call normal anyways…

            last pid: 39981;  load averages:  0.20,  2.09,  2.40      up 0+01:57:48  12:50:25

            CPU states:  1.9% user,  0.0% nice,  2.6% system,  0.7% interrupt, 94.8% idle
            Mem: 123M Active, 16M Inact, 40M Wired, 448K Cache, 28M Buf, 564K Free
            Swap: 1024M Total, 856M Used, 168M Free, 83% Inuse, 600K In, 700K Out

            PID USERNAME PRI NICE  SIZE    RES STATE    TIME    CPU COMMAND

            I tried doing a control c to break the top session and gain access to the command line again, it worked but its about a full minute delay for the commands I type to appear on the screen.  My best guess is the swap is the problem, but I'm not sure what about the captive portal is filling it up,  I did see that before it crashed a whole bunch of php commands were executed and the res state changed after about 2 sec to pfault.  I tried and garner more information on the next run w/ it.

            Update: before I rebooted the box, I got a ps -A off and here is what I got (deleted several entries that are irrevalant from the top to shorten the post):

            So that is what is filling up the swap, why so many are starting, I'm not sure, shouldn't that be prevented by the max connections? 
            Is there possibly something wrong with the index.php that is causing it to spam itself a billion times?

                @Justinw:

                This is the latest, this time it didnt' kill my ssh session, but it won't respond to additionall ssh or web gui requests, it looks like something is causing the swap partition to overflow, 856M used isn't what I would call normal anyways…

                last pid: 39981;  load averages:  0.20,  2.09,  2.40      up 0+01:57:48  12:50:25
                206 processes: 103 running, 93 sleeping, 6 zombie, 4 lock
                CPU states:  1.9% user,  0.0% nice,  2.6% system,  0.7% interrupt, 94.8% idle
                Mem: 123M Active, 16M Inact, 40M Wired, 448K Cache, 28M Buf, 564K Free
                Swap: 1024M Total, 856M Used, 168M Free, 83% Inuse, 600K In, 700K Out

                PID USERNAME PRI NICE  SIZE    RES STATE    TIME    CPU COMMAND

                I tried doing a control c to break the top session and gain access to the command line again, it worked but its about a full minute delay for the commands I type to appear on the screen.  My best guess is the swap is the problem, but I'm not sure what about the captive portal is filling it up,  I did see that before it crashed a whole bunch of php commands were executed and the res state changed after about 2 sec to pfault.  I tried and garner more information on the next run w/ it.

                Update: before I rebooted the box, I got a ps -A off and here is what I got (deleted several entries that are irrevalant from the top to shorten the post):

                So that is what is filling up the swap, why so many are starting, I'm not sure, shouldn't that be prevented by the max connections? 
                Is there possibly something wrong with the index.php that is causing it to spam itself a billion times?

                Something is pounding your CP with new sessions… May want to locate the client in question.  Either that or limit the maximum connections per client further.

                  I had just the same problem some time ago. The solution was to close down Captive portal. After that CPU usage returned back to normal. (5-10%). The box was a firewall for a lan party with about 110 attendants. i can't post any info about the processes since the box is not online anymore but I had the same problem as Justinw.
                  Everything was deadly slow and there were loads of these "39542  ??  RL    0:00.51 /usr/local/bin/php /usr/local/captiveportal/index.php" php processes.
                  The cpu usage also went 100%

                  Edit: The version I am using is 1.0.1

                      When I made this post, the snapshot I was using was only 1-2 days old, I haven't been able to try it with more recent snapshots, but should be able to soon, let you know then what happens.

                        Same problem occurs on a WRAP box when capitive portal is enabled on the OPT1 wireless interface without using RADIUS only the local user manager.

                          Anybody please test with the latest snapshot. Fastcgi was enabled for the CP webserver wich should speed things up.

                            I've tested it, I also added an additional 512 ram to the server as well.  The usage still hits 100, but it hasn't crashed the server yet, and watching top, the 100% times are just spikes, not holding steady anymore.  No more than 5 requests or so get lined up in top before they all get cleared out.  Still pretty intense but seems to be working better. Thanks for the fix

                              Sullrich mentioned in the past also that he runs a setup with 5,000 users using the CP.  I'm running a lot less users (about 10-15 times less).  Anyone else that could advise on hardware specs for 250-500 users with a cp would be helpful.  Right now it may be somewhat skimpy 1.5 ghz duron with 768 ram. The CPU is pegged with 3-4 users hitting the CP.  Right now max concurrent connections is actually set to 1.  If I understand right this means a single user can only open 1 thread, and the max is open at once is either 4 or 16, not sure which?    If there are ways to optimize the portal that would be helpful to know about as well.  Thanks in advance.

                                I am having the same issue with a 3G Pentium with 2G of memory and 2G swap space. I have not had issues with the CP until today. CPU was 100% and swap space was totally consumed and the the system completely locked. After reboot the system would work for approximately 5 minutes and then reinitiate the same process. After man frustrating recycles, I disable CP completely. Any assistance will be greatly appreciated.

                                Thanks,

                                  Any abnormal traffic coming in through the CP enabled interface that is flooding the CP page? Also what does top report when it starts to freak out?

                                    Also check the state tables.  How many states are active to the captive portal.

                                    I have found a lot of environments that have viruses and such that are making outbound port 80 connections that end up getting sent to the captive portal.  What this does is overwhelm the machine due to the amount of requests a second that some viruses attempt.

                                    If you find that clients are making too many requests a second limit the client connection count in the Captive Portal settings screen.
