Written for Java 7 but applies equally later versions of Tomcat. Mark On 01/03/2022 13:49, Rengaswamy, Nagarajan wrote:
Hi Team, Currently we are running 6 applications in Tomcat version 8.5.70 Our Linux Infra - memory size allocated like Entire memory 3GB, In that 1.5 GB as Heap size and 512 is for XX:MaxMetaspaceSize. Java version as 11. No performance related issue while application runs in peak load. But when we deploy the any one of the application while running tomcat, first deploy get success and next deploy is throwing like "Exception in thread "<app-name>_Worker-3" java.lang.OutOfMemoryError: Metaspace" Based on our investigation, heap dump shows _3_ instances of the ParallelWebappClassLoader consuming more memory which is causing this issue. Currently we are doing server restart before deploy as workaround now. Kindly suggest is there any open issue which needs to be addressed by Apache Software Foundation? or provide solution to overcome this issue. Thanks!
