Out of memory error in JCO

[Former Member]

Hi All,

In my application I am executing an RFC

Caused by: java.lang.OutOfMemoryError: Java heap space

        at java.lang.String.valueOf(String.java:2868)

        at java.lang.Thread.getName(Thread.java:1150)

        at com.sap.conn.jco.rt.ClientConnection.acquireBusyState(ClientConnection.java:198)

        at com.sap.conn.jco.rt.PoolingFactory.releaseClient(PoolingFactory.java:607)

        at com.sap.conn.jco.rt.ConnectionManager.releaseClient(ConnectionManager.java:189)

        at com.sap.conn.jco.rt.Context.releaseConnection(Context.java:288)

        at com.sap.conn.jco.rt.RfcDestination.execute(RfcDestination.java:917)

        at com.sap.conn.jco.rt.RfcDestination.execute(RfcDestination.java:884)

        at com.sap.conn.jco.rt.AbapFunction.execute(AbapFunction.java:302)

Could you please let me know why I am getting this error, I guess some of the resources are not getting cleared in JCO

Thanks Sriram for the attention. But I am not able to access those links, it is asking for user name and password which I don't have. Could you please help me on this.

Hi RCR

It require SAP Service user id (S-user id and password)
