Just got this when updating manually with suricata-update. Running with –no-test ran fine..rules worked fine.. 
29/9/2025 – 08:13:59 - – StateQueue behaving weirdly. Fatal Error. Exiting. Please file a bug report on this
29/9/2025 – 08:13:59 - – Suricata test failed, aborting.
29/9/2025 – 08:13:59 - – Restoring previous rules.
Worked fine without –no-test on Friday.
What version of Suricata?
8.0.0 and 8.0.1 ….20 character rule is kinda silly.
Are you able to (privately) share your ruleset? It seems to hit some kind of internal error condition.
Can I try running in….like…super verbose mode first? I can gather up the rule in the mean time.
I’m having the same issue; started sometime over the weekend, I’m using the ET PRO ruleset, with 7.0.12 version of suricata (via security onion).
I was trying to get a stack trace, but gdb wouldn’t let me set a breakpoint on util-mpm-ac-queue.h:86
I just pruned all of the updated and new rules from late last week “sed -i’’ ‘s/.*2025_09_26.*//’ ./all.rules” and suricata was able to start up. because some of those rules might be in ETPRO it might be difficult to troubleshoot.
