[asterisk-users] Server locking up again

[whois wes]

Hi all,

We have been having stability issues with one of our servers, a Dell
2850.  The machine has been locking up a few times a week for the past
several months, except for a two month period when we were running on
a Sangoma card (we have since moved back to Digium hardware).  The
machine was running Fedora Core 4, minimal install, and Asterisk
1.2.4/Zaptel 1.2.5 (no libpri, we're on robbed-bit T1s).  The server
has a TE410P in it, and I have disabled ACPI and the framebuffer.  We
had also moved from the onboard NIC's to PCI based NIC, but that
didn't seem to make any difference.

Last week, we received a replacement server and built it around
Asterisk Business Edition A-2.5.  We moved to BE as a desparate
attempt to fix some sound quality issues (totally separate from the
stability issues), and, for the most part, it's worked like a charm.
This machine is running a Netgear Gig-E NIC and has the onboard
network interfaces disabled, which was Digium's suggestion from a few
months to help the stabillity of the system.  This is also a BRAND NEW
2850 and has been in use since Friday July 14th.

Just a few minutes ago, the system locked up, displaying the same type
of errors that it did months before.  A picture of the screen (best I
can do right now) showing the errors is here:

The whole point of this is to get as many people to see the error as
possible so that we might have SOME idea of what is going on.  Also,
we are technically on an unsupported OS, as FC3 and RHEL 3 are the
only two supported distros for BE.

Please let me know if you have any questions or need further info.

Thanks,

Wes
