Hi, Meridoff I've asked for a complete list of modules to see what is inspectors are used. Anyway, core file would be very helpful, if you can share it. Also, maybe you can run snort with -v option (verbose output) to see what the configuration is. How many processing threads (-z option) you setup for your snort?

Can you run the following commands and share their output, please:
snort --list-modules snort --list-plugins
Also, can you provide the core file if it is available?

Can not found why, cause this function called from many-many places and in term stage too.. May be It's possible to fix it. Though I can not replay this bug. It happened only 1 time for now. PS: please remove my previous bug-report(wrong theme: "snort2 ...") with the same text but invalid theme ("snort2" instead of snort3) Thanks. _______________________________________________ Snort-devel mailing list Snort-devel () lists snort org<mailto:Snort-devel () lists snort org> https://lists.snort.org/mailman/listinfo/snort-devel Please visit http://blog.snort.org<http://blog.snort.org/> for the latest news about Snort!
