Public bug reported:
After upgrading from linux-image-2.6.32-43-server to
linux-image-2.6.32-45-server, we started experiencing intermittent lockups on
one of our servers: TCP connections frozen, no pings for 5-10 minutes,
everything fine afterwards. Issue happens 1-3 times a day, usually under loads
over 2.0.
Server is a dedicated bacula server, usually no significant load during the day.
Nothing in dmesg or syslog.
Based on the Ubuntu kernel changelog, I'd guess network TSO or a SCSI problem.
As this is not a full-time critical server, we can do some testing.
Regards,
Tamas
