In a cvs version of pre2, which is newer than pre2, on one machine, after some time of inactivity, freeradius does not seem to answer at all- sometimes, not reliable reproducable. Freeradius has a lot of database connections to mysql, maybe they are the culprit for that behaviour? stracing freeradius gives: # strace -f -p 29757 Process 29807 attached with 51 threads - interrupt to quit [pid 29757] --- SIGSTOP (Stopped (signal)) @ 0 (0) --- [pid 29758] --- SIGSTOP (Stopped (signal)) @ 0 (0) --- [pid 29759] --- SIGSTOP (Stopped (signal)) @ 0 (0) --- [pid 29760] --- SIGSTOP (Stopped (signal)) @ 0 (0) --- [pid 29761] --- SIGSTOP (Stopped (signal)) @ 0 (0) --- ...

They are not answered. Any idea, what's going wrong here or how to track that down? I already tried nohup gdb -x gdbargs /sbin/radiusd & with gdbargs containing: run -AX bt but was unable to reproduce that situation in this context. Running radiusd under gdb's control seemed to solve that problem, maybe that's not the final solution. Norbert Wegener
