Crash report

Crash report uploaded here for discussion

Seems to be a "Panic String: page fault" error. I can't make sense of it, so uploading it for the gurus to decide if this need to go to redmine as per the help pages.

Device is an SG6100

Please let me know if anything else is required.

Looks like it's this: https://redmine.pfsense.org/issues/14431
Do you have IPv6 enabled on any of those interfaces that went down?

alnico

@stephenw10 Yes, I have IPv6 enabled on all interfaces.

It generated a new bug report after I disconnected the WAN ethernet cable.

Mmm, that looks like the same crash type.
WAN is ix3 there?

alnico

Yes, WAN is on ix3

A workaround for this just went into 24.03 snapshots and should be in the next build if you're able to try it.

alnico

@stephenw10 Thanks, I will look forward to when it's released.
