Last time we had these problems was a valuable lesson. Fat chance it's the trace calls in the pool code. All code paths starting in serverchild.c,active_child_sig_handler need to be reviewed for signal safety. I don't have the list of safe calls handy, but the trace calls in the pool code are very much suspect. Goood thing you caught this. Could you file a bug please? ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0000208 glibc error in dbmail_pop3d ====================================================================== ---------------------------------------------------------------------- aaron - 03-Jun-06 06:48 ---------------------------------------------------------------------- Added a more significant comment to active_child_sig_handler.
