Chances are that that the unreleased CS is a symptom, not the cause of
your  problem.  Armed with this possibility, Ipswitch could do a quick
code  review  and  check  to  make  sure  that all CSs are released in
"normal" operation. But any application making use of objects like CSs
can  create  orphans if it crashes before functions complete and clean
up after themselves.

Yeah, yeah. Sounds like a good way to make you move to XP.

There  is  a  slightly later ODBCUSER.DLL, I believe. Contact Ipswitch
for it.

Review your observed symptoms for us:

- Are you still seeing multiple POP3D services, as you once mentioned?

- Any consistency to the last successful session before a hang?

-  What  happens  when  you  Telnet on 110 during these situations and
attempt a manual session?

- Is POP3 becoming unbound from the IP altogether?

-  What  DB  are  you  using,  and have you tried using another DB for
testing?

- What MDAC version?

- What ODBC driver version?
