Hi, I am seeing the below PermGen space issue in tomcat catalina.out file. Currently i am running Apache Tomcat Version 7.0.59 on CentOS release 6.8 (Final) java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
Exception in thread "http-bio-8080-exec-120" java.lang.OutOfMemoryError: PermGen space Exception in thread "http-bio-8080-exec-165" java.lang.OutOfMemoryError: PermGen space 2016-11-28 13:40:30.543 ERROR 19011 --- [o-8080-exec-110] o.s.boot.context.web.ErrorPageFilter : Forwarding to error page from request [/push-notifications] due to exception [PermGen space] java.lang.OutOfMemoryError: PermGen space Is there a way to debug PermGen space issue and are there any tools to debug the same. Currently i have set -XX:MaxPermSize=1024m. How do i determine what value should be set for MaxPermSize? Any help will be highly appreciable. Please do let me know if you need any additional details. Thanks in Advance Regards, Kaushal
