This is my first post to the FreeBSD mailing list, and unfortunatley its
because I've been having a vexing problem with one of my servers.
The machine in question is a Dell PowerEdge 2850 w/2 3Ghz EMT64 Xeons,
2gbs of ram, a Perc 4e/Di w/6 300GB drives.
This machines primary function is as a mail server running Exim.
Below is a DMESG from this machine.
This machine is running the AMD64 port of freebsd, and what is happening
is often when the volume of incoming mail gets pretty high, the machine
will panic and reboot. I have tried to capture a dump but it always fails
dumping before it completes, usually before its dumped more then 24MB. The
few times that I have seen the console when its happened the panic was
something to do with UFS. I have upgraded the bios and firmwares on
everything, and that increased the stability of the machine. I also turned
off soft updates on all the file systems, which also further increased
stability, however there is still a problem. Any
pointers/hints/tips/solutions would be greatly appreciated. Also, if more
information is needed let me know and I would be happy to provide it.
Thanks in advance for any help you may be able to give.
