>Organization:
OmniTI Computer Consulting, Inc.
>Environment:
FreeBSD ecbuild-16 5.3-RELEASE-p4 FreeBSD 5.3-RELEASE-p4 #0: Mon Jan 17 19:18:11 UTC 2005     root@ecbuild-16:/usr/obj/usr/src/sys/EDGE750b  i386
>Description:
After several minutes of intense disk I/O and network I/O our MTA induces a kernel panic.  Despite the use of dumpon, no image is available for savecore upon reboots.  All testing on dual processor Xeons.  Repeated with and without hyperthreading enabled, with custom kernel and GENERIC and GENERIC with SMP on.

Problem does not occur if explicitly linked against libc_r.
>How-To-Repeat:
Run /opt/ecelerity/sbin/ecelerity under production load.
