---------------------------------------------------------

Hi,

This issue was fixed in Stratos 4.0.0. Here I have attached the CEP extension patch. We need to apply the patch changes to Stratos 4.1.0 as well. This fix depends on the siddhi core fix which was done to the siddhi-core_2.0.0.wso2v4.jar. So we need to wait for the CEP release because the fix done to the siddhi-core_2.0.0.wso2v4.jar is currently not available in nexus.

Thanks !

> We have observed this issue on multiple testbeds where we observed VMs were being re-spawn after Stratos has been running for about 7-9 days. Wso2carbon log shows numerous OutOfMemoryError. Memory dump was auto-generated when this happened.
