Hi All,

We are facing frequent OOM issue in Production SOA server instances.

we have configured the JVM arug like below Is this the correct configuration or else any thing we need to add avoid frequent OOM error.

/usr/java/latest/bin/java -Dprogram.name=run.sh -server -Xms4096m -Xmx4096m -XX:PermSize=256m -XX:MaxPermSize=512m 

Below restarting the server i have taken the Heap history.
Heap Configuration:
   MinHeapFreeRatio = 40
   MaxHeapFreeRatio = 70
   MaxHeapSize      = 4294967296 (4096.0MB)
   NewSize          = 1310720 (1.25MB)
   MaxNewSize       = 17592186044415 MB
   OldSize          = 5439488 (5.1875MB)
   NewRatio         = 2
   SurvivorRatio    = 8
   PermSize         = 268435456 (256.0MB)
   MaxPermSize      = 536870912 (512.0MB)

Heap Usage:
PS Young Generation

   free     = 5468568 (5.215232849121094MB)

   free     = 70930224 (67.64433288574219MB)
   73.60221155678353% used

I suspect some generation ration configuration is worng, Could you please correct me if am wrong.
