Hi list,

 We have a backup server Dell Power Edge 1850, One Xeon 3.6 Ghz, 2GB Ram,
attached to one storage PowerVault 220 and one LTO tape drive, running
STABLE from start of June.

This machine basically runs FTP Server, NFS Server, compress directories
using tar and gzip and run some perl scripts. Some from now this machine is
presenting random freezes, then I compiled a kernel with:

makeoptions     DEBUG=-g
options         KDB
options         DDB
options         INVARIANTS
options         INVARIANT_SUPPORT
options         WITNESS
options         DEBUG_LOCKS
options         DEBUG_VFS_LOCKS
options         DIAGNOSTIC

yesterday the machine freeze completely, no ping, no keyboard response, I
have to do a hard reset (hold power off button) to bring this back.

Today happened again and this time they break to debbuger and I can get a
dump that follow.

Excuse-me by sending images. This is because I don't have a serial cable to
plug on the machine, they are on a Datacenter and usually I have only remote

Any help is appreciated to discover if this is a hardware or software
