Hi there,
after moving to .50 version from a very stable .20 one, on my OS/390 V2R6 ADSM
Server I had a strange problem.
Sometimes, the ADSM server doesn't accept any session from the clients; they all
ends with msgs:

TcpOpen: TCP/IP error connecting to server.
 sessOpen: Failure in communications open call. rc: -50
 ANS1017E Session rejected: TCP/IP connection failure

I'm not able to connect to the server neither via command prompt nor using the
Web Admin client.
The only thing I'm able to do is sending commands through the MVS console but Q
SESS shows
no session active. I opened a pmr with IBM support centre, they suggest me to
keep a TCPINFO trace
and increase MAXSESSION parameter.
When it happens, the only thingh to do is close/reopen of the ADSM server (not
very good).
Anyone has an idea?
Thanks in advance
