Suricata process dying due to hyperscan problem

could you tell me if the contents of this directory are the same as mine pls?

While not exactly the same, the failure locations I see in both of the
suricata.corefile back trace results look eerily like this old bug in that the failure is in the app-layer protocols section: https://redmine.openinfosecfoundation.org/issues/4273.I wonder if there still might be an issue lurking in the logic even though the originally reported bug was fixed ??
I've sent both back trace results and @kiokoman's
gdb.txtdump to the upstream developers asking for any insights they may have. -
@bmeeks Happy Holidays!!! I wanted to message you to say that.
Make sure to upvote

It looks like file sizes differ. I'm running pfSense 2.7.2 CE in this VM.

June 30 for 2.7.2 files is too early. Mine show December 16 dates, which coincides with the day I updated this particular VM to 2.7.2 CE.
My file sizes agree 100% with those posted by @kiokoman. Your file dates of June 30 agree with the rollout of pfSense 2.7.0 CE. The 2.7.1 CE was released in November of this year.
You might want to remove the Suricata package from your VM, then run this command to be sure the Hyperscan library is also removed:
pkg info hyperscanIf anything other than something like "not installed" comes back, then manually remove Hyperscan with this command:
pkg delete hyperscanYou having an older library might be why you are getting the segfault instead of the same fatal error -1 termination that @kiokoman and most others are seeing.
Now reinstall Suricata and you should get the correct latest Hyperscan library.

@bmeeks, I now have the same file sizes and dates. Would you like me to again load the debug package or do you have all that you need now?

It would be interesting to see if now instead of a segfault you get the fatal error termination that @kiokoman is seeing.
You do not have to install the debug package version for that test unless you just want to. I'm hoping maybe your segfault was an issue with the library compilation (being possibly from an older pfSense kernel build) and not a different manifestation of the same Hyperscan error.
So, just set the Pattern Matcher to Auto and attempt to start Suricata. If it dies immediately (or later), check the
suricata.logfile to see if you have the "Hyperscan returned fatal error -1" message. If you still get a Signal 11 segfault in the system log, then color me thoroughly flummoxed

Just had Suricata crash with this messag on my Netgate 8200:

@Negan I've had similar in other php files and these seem to be related to trying to do too much compared to the memory allocated for PHP. Were you trying to load a very large log file in Suricata Logs View? May be related to the specific interface and log type.
I'm no expert on this, so someone else may correct me, but maybe look at the log size and rotation settings for that interface and lower them so they cycle out more frequently, especially if it is a really busy interface?

@sgnoc
Your probably right, just never seen this after Suricata crashed before..... -

Please post this in a new thread so as not to pollute this one with completely unrelated information. Do you see anything in the error report you posted that says "Hyperscan"? If not, then posting in this thread that is titled "Hyperscan problem" breaks standard forum etiquette. Replies to a thread should stay on the topic of the thread.
With 248 posts, this thread is rapidly becoming too long, and burdening it with unrelated issues only makes that worse.

Well this was in the log,
74327 - W#07] 2023-12-19 14:29:30 Error: spm-hs: Hyperscan returned fatal error -1.
And what I posted was there also, thought it might be related, which as you say it's not.

That error is definitely related, but the PHP one is not. This thread has gotten so large I've lost track of which user has posted something related previously and who has not.
Sorry if I sounded like the crusty old guy yelling "you kids get off my lawn!"
.Your PHP error is common to any action on pfSense that attempts to open a large text file for viewing in the PHP GUI. PHP just can't cope with large files as it must first load the entire file into memory and then stream it out line-by-line to a web client. You will need to view the file using command-line tools such as
vior transfer the file off to a PC and view with text editor apps there. The PHP process on pfSense has a fixed memory size that is somewhat independent of how much RAM you might actually have installed on the firewall. In other words, you will get that error no matter if you have 2GB of RAM or 64 GB of RAM installed. -
The thing is I was not looking at any files at the time, anyway, I just Deleted Sucicata as it's been of no benefit since 23.09. so I won't need to post here again, best of luck tracking down the error..

You had to have been attempting to view one at some point. That's the only way that error can appear. The thing with the PHP errors, though, is that the Dashboard is the only place they will be shown. So if you tried to view a log two or three days ago, but never visited the Dashboard in the interim, then the next time you do open the Dashboard you will see the PHP error that was recorded in the past.
According to the error, someone attempted to view a log file from the LOGS VIEW tab at this date and time: 19-Dec-2023 13:50:29 Australia/Sydney.

@bmeeks
Well I only installed Sucicata again today and it was crashed and the PHP Error was there, anyway, thanks for helping.... -
@masons
i suspected you had a different version of hyperscan because i had that same crash when using hyperscan 5.4.2 instead of 5.4.0
now that you have corrected the situation I expect that you no longer have the crash/core dump but only hyperscan that fails like me -
@kiokoman and @masons:
The upstream Suricata developer team took a look at yourgdbback trace reports and has asked me to prepare a new debug Suricata package with the Address Sanitizer option enabled and let you run that for a while. That option performs a very detailed memory use analysis at runtime and can print more detailed debugging messages.I'm working on creating that build now and will test it on my system first to be sure it functions. Once I get everything ready, I will post a link to it back here in this thread.

@bmeeks
Nice, ready when you are
