I think there is a bug in bnet_thread_server that causes the Kaboom. The dlist sockfds contains the fd_ptr objects, which are allocated with alloca. The problem is that the dlist destructor will deallocate them using free (i.e. sm_free). You can see this in the backtrace, where the argument to sm_free is a pointer into the stack (0xffbff028). __Martin ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
