max_proc_per_user exceeded for uid

We have a Alpha server ES47 running Tru64 Unix V5.1-4 i.e. on 
patch kit 6.

In the past couple of days the server has started reporting the
following in the messages file and I am not sure how am I reaching the
processess limit of 4096.

I am informed by our DBA the problem appears to be caused by a Oracle
Enterprise agent which keeps on bouncing the databases.

Yesterday the DBA stopped and restarted the Oracle Enterprise agent but
only fixes the problem for a while until it starts to report these
max_proc_user exceeded messages again.

Has anyone got a fix for this type of problem?
