We've migrated some of our storage servers to CentOS 4.3 and are seeing
lockups. It *could* be hardware I know, and I'm scheduling downtime to
run memtest86+ ASAP.
2* LPFC HBA's connecting to our SAN,
dm setup for multipath to see 4*1.6TB trays
each tray as a PV in lvm2 sanvg
xfs on a 3T lv
NFS exported out as /export/work
using the 2.6.9-34 centosplus SMP kernel (3GHz P4 with hyperthreading
what we normally (~once a day) is simply
do_IRQ: stack overflow: 416
on the console and nothing else. (needs a cold reboot)
Having installed netdump (nice tool btw) we got a different error
yesterday that looks xfs / nfsd related...
any help in progressing this would be much appreciated -
