telnet session limit

[wendling]

Hello,
Openvms 6.2, ucx 4.2 eco4
We putted a telnet session limit of 300 ( ucx set service telnet /limit=300) but we still are limited to 200. Tcp/ip has be restarted.
Operator.log shows "ACP telnet request failed,
total service limit reached". Any idea ?

Thank's in advance.
Gérard.

Gérard,
Have you checked the system parameter IJOBLIM ?

Do ucx sho comm

and check for device_sockets (peak). This probably needs to be increased.

Gerard,

You may also want to check how many buffers are available
UCX SHOW COMM/MEM
and see if you are hitting some limit in there.

Another thing to look at is MAXPROCESSCNT in SYSGEN.
What is your current value (SHOW MEMORY/SLOT)?

Tank' all for those quick answers, nice to see such dynamic VMS forum.
IJOBLIM was at 250 putted 350, there are also some LAT connections ...
MAXPROCESSCNT is at 460, there where a max of 321 processes still last boot (100 days)
I will check the comm parameters ...

If it is dev_sockets you should get "process quota exceeded" when doing telnet from VMS.
But I didn't find any message in operator log.

I wonder if your restart of TCP was done.
Try ucx disable servi telnet (will kill all session) followed by ucx ena servi telnet.
Just tried it and the new limit was accepted.
