"kSMF service thread held > 25 (sec)"

We had a part of a vmware cluster go down this morning when a VMFS volume containing some iSCSI VMs apparently became unreachable for a period of time.

 

The only thing we see in the Netapp logs is:

 

Event: ksmf.svc.watchdog: "kSMF service thread held > 25 (sec) by application for table d_vdisk_lun"
Message Name :
ksmf.svc.watchdog
Sequence Number :
1420474
Description :
This message occurs when an application is taking too long to complete a kSMF operation.
Action :
(NONE)

 

Anyone seen this?

 

Would this error reflect a lockup on the Netpp side, or would this error be a side effect of the iSCSi network connectivity going away for a while? I could not find any info in Google search for this error string....

Re: "kSMF service thread held > 25 (sec)"

might be a performance issue

 

do a search for 'toolong' in the EMS log

 

Is the system sending Autosupport? If yes, you can ping me (private message) the serial number and I'll have a look

 

Is there an open case?
