Hi, the stability problems I had posted a week ago are occuring again, and I also got at least one more occurrence of the ominous assertion faileure in modcall.c Sow I would like to provide Alan with a core dump/bt, but I couldn't manage to produce one. Here's what I have tried so far: - enable coredumps in /etc/freeradius.conf (logfile confirms it) - make /etc/freeradius writable for the freerad group - change login shell of user freerad to /bin/bash for a test, login and make a 'sleep 1000' crash by sending a SIGSEGV -- this produces a core file, so ulimits should be o.k. - Look under /proc/<freerad-pid>/cwd to figure out the current working directory of the main freerad process, it's always '/'. So where should I expect to find a core dump? Thanks, Martin
