Informix DB - generating multiple connection for the same user. application hangs ...

Hi ,

We are connecting from a PowerBuilder application to Informix (AIX).
We are using only one user id, but trying to establish multiple connection for the same user.

After around 140+ connections, our application became slow. Is there any maximum limit for connecting same user multiple sessions?

If so, pls guide me how to resolve? Unfortunately this is happening in Production environment.
Pls. help ASAP.

Ours is Informix in AIX. ( 9.55C1).


Regards,
Rajiv S
