Thanks Jason, this has helped narrow down the problem significantly. From this I understand that to work around this problem, I have some options: 1) tweak my code to not allocate such a large amount of small objects 2) move away from malloc/free based c++ allocators 3) recompile libc with jemalloc I'm really hoping for 4) where I can LD_PRELOAD only jemalloc, would that be possible? Or does libc include parts of malloc/free itself inlined? I'd hate to force PowerDNS users to recompile their libc for me :-) Thanks! -- http://www.PowerDNS.com Open source, database driven DNS Software http://netherlabs.nl Open and Closed source services _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
