We upgraded our server to 7.4.3 last month (on Windows 2003 server). Our
Exchange backups (both :IS, :PF, and Mailbox) began to fail/hang on our
two mail servers. Support had us upgrade both the filesystem clients (to
7.4.3) and Exchange Modules (to 5.1.1.294) on both mail servers, but
that has not entirely resolved the problem. Our Exchange backups
continued to fail with no error messages. The group would start, but no
save-sessions would ever begin. The groups would not time out or fail,
just hang until manually aborted. If we stop and restart the processes
on our Networker Server, all the Exchange backups seem to work for a day
or two, then they start to hang/stall once again with the only
resolution we've found to be to recycle the services on the Networker
server. This is not always easy or feasible for us to do either daily or
every other day. EMC support has not been able to offer any concrete
suggestions to rectify this behavior. This also seems to affect the
filesystem backups, but we are much more concerned about the Exchange
backups. Has anyone else experienced issues with Exchange backups like
this ??

Thanks,

Paul Goslin
