Hi all,

I have a strange problem. When connected via telnet (AccuTerm),
sometimes lose the connection. This is no big deal as it is going
through the internet, so I expect to drop a session every once in a
while. But, when the session drops and I try to reconnect, I get User
limit reached after I enter my password. This doesn't make sense to
me since I am the only one on the system at the time.

After the disconnect, I connect directly to the server via Remote
Desktop and start QM Console and login to QMSYS. When I run "config"
it tells me that Max Users is 4 and 3 are available. If I "LISTU"
only my console user is listed.

What is going on and how can I correct this?

Thanks,

Rick

Hi Rick,

This may just be bad timing.

There is a long standing bug in the Windows socket library where it does not
always tell the process that is waiting for input that the connection has
gone away. It can take some time (if at all) for us to be able to detect the
lost session. We have some ideas of how to improve this situation but they
are not yet implemented.

The QMSvc service does a periodic scan to check if the sessions we think are
logged in really exist and, if not, tidies up the user table. You may have
caught it in the interval between the process dying and the cleanup.

Next time it happens, open a Command Prompt window and do
\qmsys\bin\qm -d1 > qm.log
and email me the qm.log file. (That's a digit 1 in the -d option).
