Crashing on new hardware with Fatal trap 12: page fault while in kernel mode
-
Yes, the bug is somewhat random. Sometimes the second passive FTP connection froze the whole system, sometimes it crashed and rebooted after 10 minutes of FTPing/downloading via HTTP. I haven't been able to crash the July 1st snapshot no matter how hard I tried. I'm running that now. Maybe it's worth a try for you, too.
-
OK, now I have been almost realiable able to reproduce the panic even on a kvm based proxmox machine running on a different server.
pfSense panics always when using passive FTP on any client and when actually uploading a file (i.e. writing to a FTP server). I could reproduce this multiple times now.
I guess my hardware is not the reason.
-
Did you try the July 1st snapshot, too?
-
No, but I'm about to go back to this one right now and test again.
-
@athurdent: Which build are you using?
-
This one seems to work fine:
http://snapshots.pfsense.org/FreeBSD_RELENG_8_3/amd64/pfSense_RELENG_2_1/livecd_installer/pfSense-LiveCD-2.1-RC0-amd64-20130701-1521.iso.gz -
Thanks, I downgraded using the integrated firmware update function with the full_version upgrade .tgz from that build. Let's see how that works.

Confirmed… The latest batch of FTP-related patches seems really bad, managed to crash my Alix testbox repeatedly… As simple as browsing to ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/i386/packages-8.1-release/Latest/ e.g., not even required to upload/download anything.

July 1st build - no crashes so far. Crashed almost every 15 minutes before.

I don't know. That could be coincidental.
Example. I have a machine here that I built 8 years ago and I over clocked it 8 years ago and it worked flawlessly every single day with no issues 24/7 without power offs. Later, I tried installing Linux and it would reliably crash after a few minutes, so I figured "Must be a compatibility issue with linux mint". Well, I removed the over clock settings and as it turns out, Mint is now rock solid on that machine.
So its was stable under XP overclocked but not with Mint - But it wasn't Mint's fault.
In nearly every case where an OS was unstable and I was certain it must be the OS it turned out to be hardware in in every single instance prime95 would expose that in short order. Most recently this was with a new mobo with new ram and processor and turned out the capacitors on a ram bank were weak.

I don't know. That could be coincidental.
I reproduced this on 3 different boxes (2 amd64, 1 x86) with post-July1 snapshots. Does not happen on any of them with previous snapshots that don't include the faulty FTP patches.
-
Then I guess you are right. Thats pretty solid evidence that its a problem with the patch. Makes sense.
-
I made fixes to prevent the panics.
Check later coming snapshots better from tomorrow ones. -
Sounds good, thanks!
-
Thanks, will test tomorrow…

Hi I have the same problem and reverted to 1st July version. I don't get crashes anymore but I also have problem on ftp traffic. The connections are too slow or I get a lot of disconnection from ftp server.
-
Here, too. FTP connections are very unrealibly with July 1st version.
-
Has anyone tested the latest releases? Is it safe to upgrade again?
-
Seems to be stable again, but you can always downgrade with a backup.tgz on full installs or switch slices on nano.
FTP still does not work very good with the sites I have tested, tough.
