I apologize in advance for the post, my reply by email was bounced back...

|

|

|Thanks for any help!

Lookup the Sybase stored procedure "sp_configure".  I believe there is a
parameter that limits the number of active sessions and that the default
configuration uses a value of about 25.

Sorry I could be more help, my documentation is at work.
