      Description

      This problem looks very similar to
      bug 4489387 -Xrunhprof crashed jvm or got program run to hang

      Ihac profiling their server with -Xrunhprof:heap=dump
      and the system terminates with an OutOfMemoryError.

      Here's the settings that are being passed to the JVM:

      -DDefaultCompilationConfig=en_US
      -server
      -Xms256m
      -Xmx256m
      -XX:NewSize=90m
      -XX:MaxNewSize=128m
      -XX:SurvivorRatio=1
      -XX:TargetSurvivorRatio=90
      -XX:+DisableExplicitGC
      -XX:+UseDefaultStackSize
      -verbose:gc
      -Xss256K
      -Xrunhprof:heap=dump,format=a,file=c:\hprof-results.txt,doe=y

      The OutOfMemoryError occurs after a few minutes; it doesn't happen
      immediately.

      In the following run, the system started at 17:48:38.461 and got an out of memory at 17:54:02.721. No stack trace appears to be available.

      Here's the output of verbose:gc

      They have also tried increasing permanent size to 256M in case
      perm gen is being exhausted but the system still throws an OutOfMemoryError.
