[imp] Session ID Duplicates

[meei you lee]

We are using IMP webmail. We have horede-2.23., imp-3.2.1.and Apache 
2.47 installed . PHP 4.3.2 is built as a apache dso module. We have 
three separate dedicated  web servers to serve user's  requests . Each 
web server is running  on its  Linux box.    These three web serves are 
load balanced and shared  MYSQL  database as session storage.  MYSQL is 
running on its Linux.


Once in a while we received  complains from user that  they can view 
other people's mailbox even they were authenticated as themselves. We 
suspect it is sessionID duplicates( each webmail application manages 
its own session and does not share session information with each other) 
Does anyone has  experienced the same problem? If so how to solve the 
problem  ?


Thanks
