Re: [SR-Users] 4.0.4 crash segfault when CANCEL

Can you compile with MEMDBG=1 in Makefile.defs and try again? Might be a memory overwritten issues somewhere. Look in the syslog for memory related message.

Few more details needed ... do you have memjoin global parameter set? Is the situation reproducible, or it happens sporadically?

Cheers, Daniel
