VM's very unstable..core dumping and writes to disks taking too long

$

0

 

The two VM's I have keep crashing....with the following messages in the Event logs.

 

 

Can someone guide me to track down what could be causing this? One of the messages talks about the resick.timeout parameter setting, but does not recommend changing it. The other one talks about a bug # 41568.

 

 

   

 

 

Thanks

Message

from i7ubuntu: This virtual machine has been unresponsive for more than

20 seconds and has caused another virtual machine sharing a disk with

it via SCSI reservations to believe it has died. It is therefore unsafe

for this virtual machine to resume activity, and this virtual machine

will now terminate. If a 20 second delay is not long enough to be an

accurate 'death heuristic' it can be changed by setting the

"reslck.timeout" configuration variable. It is extremely unlikely that

this should ever be necessary.

 

 

 

 

 

From the vmware-0.log I do see some of the writes taking a long time on one of the shared disks, and when that write exceeds 20 secs it seems to core dump. No idea why it's taking that long to write to those disks.
