AEM_How to identify the check session count

Issues: 

• In many cases the problem is the number of open sessions it too large. 
• At some point, it slows down processing. 

Solution :

• To find out if this is the case, run

        jps -l (to get the process id of the Java process)

        jmap -histo  | grep CRXSession (to get the number of open sessions)

Conclusion :

• If no of opened sessions count is greater then some hundred, then there is possibility of session related issues.
• Possibly a session pool is used (depending on the version of CRX / CQ there could be a hot fix for the given problem), 
• or an internal (possibly application level) cache references sessions. To analyze where those sessions are opened.
• Generate thread dump and heap dump to find out the RCA.
• Use the eclipse MAT for heap dump analysis and TDA or fastthread for the thread dump analysis.
