Strange GlusterFS problem

[Torsson]

Hi.

I have a GlusterFS server that replicates files between 2 servers. and i have the client mounted on the same servers.

And for a few days ago one of the servers got "Out of memory" and i was not able to ssh it or anything, heartbeat tok over mail, web, sql and so on but glusterfs failed on the server that was ok. And i tried to unmount the gluesterfs.vol but it was busy even if i turned off glusterfsd on that server.

I think the client was still mounted to the server with "out of memory". Does anyone know how to prevent Glusterfs from this problem if something like this happends again?
