The default max number of connections for SHM is 50 if you don't
adjust/increase it with NETTYPE. This is why the 51st user is failing, =
but
50 is fine.
Let me know if this doesn't help.

I didn't see the onconfig attached, btw. What are some of the NETTYPE
settings you tried?

Today we experienced an odd problem.

The 51st person to access the database would get the following message=
:

The appl process cannot connect to the database server dev.
(Error -25588, ISAM8

Up until that 51st user, everything was running fine. When user connect=
ions
went back down to 50 we were fine again.

The 25588 error message says:
An error in the application can produce this message. Check your
CONNECT statement and the sqlhosts file. A system failure can also
produce this message. If you can find no immediate cause for the
failure, note the circumstances and contact your database server
administrator for assistance.

The shared memory communication subsystem is down or not functioning.
Contact the database server administrator to report the problem.

We are working with the vendor that maintains the software and they hav=
en't
come up with a resolution yet. I've been trying different onconfig
parameter settings all night and haven't come up with anything either.
I've
spent the most time playing with NETTYPE. Until today I didn't even ha=
ve
NETTYPE defined in my onconfig. I have 3 different instances of IDS an=
d
they all are manifesting this same problem. I have attached the oncon=
fig
file if that will help.

I appreciate any ideas anyone can give me.
Thank you.
