> 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. Please find in the attached file (debug_info_20140922.tar.gz) the following items: Stratos logs, thread dump, screenshot showing 3 memory leak suspects. Cannot attach memory dump file here due to the size limit restriction.
