Symptoms


OutOfMemory errors are being receinved  in the Admin Server. Initially the  memory arguments were -Xms1524m -Xmx3056m  -XX:MaxPermSize=1024m . After the issue was initially observed, the customer has increased the memory arguments to -Xms8192m -Xmx8192m -XX:MaxPermSize=4096m. But this did not resolve the issue. The following is a  snapshot from the logs :
