Hi Florian,

We are testing SimpleForwardingCmisService.java under 
"org.apache.chemistry.opencmis.bridge.httpsession.sample" package, so I guess 
it is HttpSession implementation.  Correct me if I am wrong, our current the 
architecture is 1 ESB->Load Balancer->2 OpenCMIS Bridge Servers->2 CMIS 
Servers, I am wondering if we enable cookies(session stickiness on LB), then 
all transactions could possible go to one OpenCMIS Bridge server only. 

Our current session time is 5 minutes in web.xml, this may help to reduce the 
impact of "lots of unused HTTP session". I am thinking if we should reduce 
Chemistry client cache TTL from default 2 hours to shorter time or if it is 
possible we can disable client cache completely?


Thanks
Wentao

Hi Wentao,

Are you using the HttpSession or the LruCache implementation?
If you are using the HttpSession implementation, make sure that the clients 
have cookies enabled. Otherwise you are collecting a lot of unused HTTP 
sessions on the server side that fill up your memory.
