MaxDB on OpenSolaris 2008.11 resources problem

Question

Hello,
I have installed MaxDB 7.6.05.09 on a server with OpenSolaris 2008.11, an Intel Core Quad CPU, 8GB RAM and have other two PCs with JBoss connected to the database. After some time running (less than three hours) and the connections used when arriving at 80 (out of 400 available) database denied connections. When trying to access the MaxDB GUI console get the message '[...] cannot create semaphore".
These are some of database parameters:
MAXCPU = 4
MAXUSERTASKS = 400
MAXLOCKS = 32040
CACHE SIZE = 400000
Please, can someone help me with this problem?
Thanks in advance.
