OOM.hprof

Former Member — Mon, 20 Jan 2014 15:14:43 GMT

Hi ,

We have been seeing frequently Java dump OOM.hprof (Out of memory) and OOM.Addons files (around 2 GB) on the server0 and server1 nodes. These files are consuming the server space and it is effecting the performance of the applications that run on this server. Every time I need to delete these files at both the places to free up the sapce.

Our SAP Netweaver has 2 java server nodes.Our Memory VM Parameters are (I guess per each java server node)

initialHeapSize ------ 2048

Maxheapsize ------- 2048

maxnewsize ---------- 410

maxpermsize --------- 1024

newRatio ---------- 6

newsize -------------------- 410

permsize ---------------- 1024

Total Ram is 8 GB

1. Do I need to make any change in the VM parameter settings like increase the heap size etc?

2. Do I need to increase the RAM and then server nodes?

3. Is there a way to avoid this java dump on server0 and server1 nodes?

Can any body help?

Regards,

Guru.

Please check note 1289240 - How to deal with out of memory errors

Increasing the Heapsize could solve the issue, but maybe this is caused by some badly designed Java code that did consume too much memory.

Try to analyze the issue with the memory analyzer

=> Java Memory Analysis
