[Linux-cluster] Cluster services stopping

[Luis Godoy Gonzalez]

Hi

We  have a similar problem, my server is runnig three services but only 
one of them restart sometimes without reason.
We have not a problem of high load in the server.
Could  happend months or weeks without any service restart.

The only difference with the others services is a ext3 file system on 
one shared external storage.

We have other installation with similar configuration and this problem 
is not happened.
I'm checking the fs.sh script to add more debug info. I think this 
script may report same error and this may trigger the restart of service.

We have RHE4 U2 and only update rgmanager to "rgmanager-1.9.53-0"

At this moment I'm installing RHE4 U5 for testing and we try to update 
the production host later.
But my problem is that I'm not sure if this update will fix this issue.
Make an update in production is "complicated" and I will have serius 
troubles if this update not fix this issue.

Bye-bye.
Note: sorry for my bad english.
