Re: Session replication problem

[Giancarlo Frison <fr...@nimbuzz.com>]

Hi all,

This is the catalina.out. I read the post about session expiration
during shutdown, so I tried to kill -9 the process to avoid any
unexpected behavior but the outcome is the same, no session replication.
What I may do? I appreciate any suggestion. Thanks!
