I've encountered outOfMemoryError when running wso2 identity server as key manager of my wso2 api manager. I use the wso2 identity server 5.1.0 and wso2 api manager 1.10.0. Some logs that I got are : 

TID: [-1] [] [2016-04-01 03:40:28,196] ERROR {org.apache.tomcat.util.net.NioEndpoint$Poller} -   
java.lang.OutOfMemoryError: Java heap space

TID: [-1234] [] [2016-04-01 04:23:05,784] ERROR {org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask} -  Error while running deployment scheduler..  
java.lang.OutOfMemoryError: Java heap space

TID: [-1] [] [2016-03-30 08:57:46,404] ERROR {org.apache.directory.server.ldap.handlers.LdapRequestHandler} -  ERR_732 Cannot process a Request while binding 

TID: [-1] [] [2016-04-01 09:26:25,208]  WARN {org.apache.directory.shared.asn1.ber.Asn1Decoder} -  The PDU has been fully decoded but there are still bytes in the buffer.

I've tried to force kill the wso2is and started it, but sometimes after restarting, the problem appears again.

How can I solve this?

  • Did you checked the heapdump? – Thusitha Thilina Dayaratne Apr 01 '16 at 04:13
  • @ruccive, How much heap size you have allocated? We need atleast 512 MB. Check [Installation Prerequisites](https://docs.wso2.com/display/IS510/Installation+Prerequisites) – Abimaran Kugathasan Apr 01 '16 at 05:59
  • @AbimaranKugathasan : i didn't modify the default setting, so i guess -Xms 256 -Xmx 1024 (from what i read in wso2server.sh). should i raise it to higher value? – rucciva Apr 05 '16 at 03:31

Please try with -Xmx 2048 in wso2server.sh
