It would appear that you are running out of memory (?RAM+swap?) and OOM-Killer is being invoked. If you have sysstat installed you should be able to review the sar data for the day(s) the problem(s) appeared. To get a better (easier to read) picture of system activity, you can use kSar to graph the sarxx file(s) for review.

To add to what rayfordj said, you don't provide alot of details here, like what that server is RUNNING, part of a cluster or not, how often this happens, if anything changed, etc.

I've seen oom get called with Oracle servers before. But the best thing you can do, is to CALL REDHAT, since you've got RHEL, you're paying for support and access to their knowledgebase.

Thanks rayfordj and TB0ne. TB0ne I will also log the case in REDHAT on this issue as this server i have not put it in production it's just in initial installation and configuration stage so for first aid perspective I have posted my query. rayfordj this server having memory 12 GB and I have assigned the swap also 12 GB. This server having Intel Quod core cpu, as I mentioned in above line that this server is in initial stage I have only configured the RHEL cluster suite and I have assigned only VIP in a resource not any mount point or application script for testing purpose. So then why this server gets hang if I have not put so much load on this server. Please advice...

Thanks Rgd

12GB for swap is VERY high, and I've seen server have problems loading with more than 8GB of swap.

You still don't say what this server is doing, what you are loading on it, or provide many details. If it was me, I'd reload the OS, and drop swap to be about 4GB...but again, we can "advice" you to call RedHat. THEY will be able to look through system dumps, logs, etc., and tell you what's going on.
