Segfault on pfSense related to LuaEngine #5929

Closed Taralas closed 3 years ago

Taralas commented 3 years ago

Using pfSense 21.05.1-RELEASE (amd64) on a Netgate SG-4860, with v.5.1.210927 from the ntop pkg repo, I am receiving the following error approximately 15-45 minutes after starting:

WARNING: Script failure [/usr/local/share/ntopng/scripts/callbacks/system/discover.lua][index] Segmentation fault

I was originally working with alfredo.cardigliano via the Discord on this issue. I have a coredump from a previous version that was also exhibiting the same behavior, which I would love to attach, but GitHub is choking on after being compressed

cardigliano commented 3 years ago

@Taralas I remember you had a bunch of failures, some of them were due to the inability to find lua modules (we pushed a fix for this some time ago), could you confirm you are no longer experiencing those failures? Is this the only message you get now, or you have more logs? Thank you.

Taralas commented 3 years ago

That is the only message that I am receiving at this time.

cardigliano commented 3 years ago

Please drop an email to cardigliano at ntop.org, I will send a debug binary

cardigliano commented 3 years ago

ntopng binaries were crashing upon application startup until yesterday's release. Today's version seems to be running and it is executing (with debug symbols) at the user premises. We will wait for updates.

Taralas commented 3 years ago

Sorry on the lack of updates. Work has been a bit difficult. I was able to get some time this morning, and ran the last debug build, and had two crashes, both with no stack traces:

Not a problem. Real troubleshooting takes time 😉

@Taralas Can you please update and report: we believe we have fixed the issues

simonemainardi commented 3 years ago

Other users have reported that the issue has been fixed on pfSense. So I'm closing for now, asking @Taralas to check and reopen if necessary.

Taralas commented 3 years ago

Sadly, I am still getting nightly crashes, but I do not believe they are related to the lua issues.
