Check your TCP timers in NMMGR.  They should be:

Path:  NETXPORT.GPROT.TCP
[Y]       Checksum Enabled (Y For Yes, N For No)
[4096 ]   Maximum Number of Connections

[1  ]     Retransmission Interval Lower Bound (Secs)
[360  ]   Maximum Time to Wait For Remote Response (Sec)
[2  ]     Initial Retransmission Interval (Secs)
[8  ]     Maximum Retransmissions per Packet

[600  ]   Connection Assurance Interval (Secs)
[4  ]     Maximum Connection Assurance Retransmissions

To have them take effect, you need to stop/re-start the network. Since
getting the box that quiet is nearly the same thing as rebooting, I
normally recommend rebooting....

If you're still having issues, <plug> I recommend you contact Allegro for
assistance </plug> :-)         - donna
