If you did not manually upgrade glibc, the one that comes with RH7.x does not have NPTL, so LD_ASSUME_KERNEL has no effect. OTOH you had machines (likely those ones) with a *huge* RSS, that is typical NPTL effect. If the RSS grows over a certain limit, the OOM killer in the kernel kicks in and kills your hungry application. You can try to get 1.18: http://www.xmailserver.org/xmail-1.18.tar.gz and build it in debug mode by replacing -O2 with -g and removing all the "strip" lines from Makefile.lnx. Then you can add "ulimit -c 300000" to your XMail startup script and run it again. Note that with RSS like your the core might not even fit the 300MB limit though. - Davide - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
