100% CPU usage !

prashant punekar
Hi,

Here is the error log which takes the CPU usage to around 100%.

2010-07-09 17:17:58,551 (ContainerBackgroundProcessor[StandardEngine[default-server]]) [ CartEventListener.java:74 :ERROR] Could not get the current visit, not saving abandoned cart info.
2010-07-09 17:17:58,553 (ContainerBackgroundProcessor[StandardEngine[default-server]]) [ CartEventListener.java:74 :ERROR] Could not get the current visit, not saving abandoned cart info.

This error is thrown inside a method sessionDestroyed() of class CartEventListener.
The cause of the above error is because we have commented out the visit hits as we do not store any visit hits.

The main concern is the session gets destroyed and a new session gets created.

Can someone please throw some light on the session creation/destruction.
I have observed for the same browser window and the same request ofbiz starts new sessions which is confusing.

Appreciate your fast response.

Thanks in advance.

Regards,
Prashant

One of the main causes I have seen for multiple sessions being created is when your html head contains html encoded hrefs within the link elements.  

A side effect of the security enhancements made a while back to OFBiz is that sometimes things that shouldn't be html encoded (such as urls) are being encoded automatically by OFBiz.  I can remember why this causes a problem, I think the browser fails to send the session cookie with the request because of the strange url.

I meant to say: I *can't* remember why...
