Good morning!

We have been seeing occasional core dumps from bro, currently running on 2.5-870.  We've tried a few things to reproduce it on-demand but haven't been successful.  We were wondering if you might have some insight into the crash.  This is the backtrace we get:

#0  TableEntryVal::ExpireAccessTime (this=0x9b349bd32ebb5614) at /hostname/bro-devel-src/src/Val.h:741
