Hi All, I was able to reproduce this issue with carbon core server. I am getting "java.lang.OutOfMemoryError: PermGen space" as mentioned in https://wso2.org/jira/browse/CARBON-9145. In carbon core server if we invoke "Graceful Restart" several times we can reproduce this issue (In my machine i was able to reproduce the issue by invoking 3 times). In-order to narrow down the issue i un-installed LDAP specific (apacheds and org.wso2.carbon.ldap) features and connected user manager to a h2 database. Still i was able to reproduce above error after 3 attempts. Therefore i doubt, whether this issue has an impact from LDAP server. When monitoring memory usage in each restart, i observed that memory usage increases about 1-2% for each attempt. (I did the same setof actions in each attempt). I am not quite sure what could be the root cause for the memory increase. We need to further investigate this issue.
