Out of Memory Issue with our IS

We are getting the following error. java.lang.OutOfMemoryError:GC overhead limit exceeded. Current WM is version 8.0 SP1. Any recommendations ? current configuration for memory is 4Gmin and 4Gmax heap… with a 512M perm size. Our thoughts are due to large number of big files 40 - 50 mg hitting at the same time.

You may need to do big document handling, don’t load all the data in memory.

Hi Jack
When exactly this out of memory error is happening when server is running or when it is coming up from shut down ?

Things to do :
Try getting the thread dumps and check the CPU utilization when you see the logs out of memory errors…
Which version of JVM you are using ??
Did you do any recent changes in the settings ??
Check whether you have enough swap memory and disk space for broker documents…check the statistics of broker log and storage file size ??
