Hi,

Right, that's a problem in the session serialization. But does that effect the working of the Explorer?

Best regards,

[jasminindia]

It is working fine. just wanted to confirm it is not stopping any process.

Thanks for quick reply

When will this serialization problem be fixed?  It causes an alert email to be sent whenever I shutdown and restart tomcat.

I'll verify and fix it.
