Hello list, I've some problems with two dell sc1425, using two u320 scsi hardisks, freebsd 6.1, gmirror raid1 mounted at /, a dual core xeon 3.2ghz:
- the production server started to get really really slow last week
and started to print those [0] messages to dmesg
- after I rebooted that server it seemed to work normally
- yesterday it freezed or was extremly slow:
* no services via tcp where reachable
* it was still reachable via icmp
* it was *not* possible to login via console
* it was possible to switch virtual consoles
* after rebooting it, it hung in the fsck, which did not print any
status messages
* we rebooted it in single user mode, where we could see the fsck
doing its work
* we rebooted it then again in normal mode and after short time for
fsck it is up and running again
I am wondering whether this is a hardware or software problem. The
system is a heavily used mailserver offering
imap(s)/pop3(s)/smtp(s)/webmail.
I am currently somehow deterred to continue using this server, so any
hint how to debug this issue are appreciated.
Sincerly
Nico
