Well, it appears to me you have a performance issue (resource issue) causing the failure.

It could be a disk error, a bus error, or a file system error causing the I/O problem; or like the message says, it could be a memory issue.

So, you should probably look in your syslog files and boot messages for errors related to the above recommendations:

Code:

  
        Recommended Actions
        Examine I/O and memory activity on the system
        Reduce load on the system
        Tune virtual memory parameters

I would start at the top (look for errors in log files) first.
