Very interesting bug report.... I will currently stick with my current configuration, but if this confirms to solve the prolem, it could explain some oddities Remy wondered upon.... Cheers, Noam

Our testing (LD_ASSUME_KERNEL=2.4.1) is in progress but too early to confirm anything. Another option is to stick with the NTPL, using an updated glibc. Check out RH errata ; "A bug in pthread_cond_wait() which could cause programs hangs in some cases" https://rhn.redhat.com/errata/RHBA-2003-136.html If anyone tests this please drop the list a mail..

Very weird symptoms, though. The only explanation for the bug is if the thread waiting on the socket just vanishes (there's no way it can go out of the blocking accept loop otherwise - I reviewed that quite extensively ;-)). Q: would the assume kernel 2.4 work as well ? I believe it would, but it could be worth confirming it eventually. This is not critical, obviously. -- xxxxxxxxxxxxxxxxxxxxxxxxxxxxx Rémy Maucherat Senior Developer & Consultant JBoss Group (Europe) SàRL xxxxxxxxxxxxxxxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
