Database may be abnormal shutdown when the -n has been reached or exceeded.

The server process (_mprosrv) to which the client who exceeded the -n is connected goes down.

FACT(s) (Environment):
Progress 8.x
Progress 9.1A
Progress 9.1B
Progress 9.1C
CAUSE:
Bug# 20010711-004
FIX:
Upgrade to Progress 9.1D or higher. If database is Progress 9.1C apply the last patch to the 9.1C install.
To workaround the problem increase the "-n" parameter to a value that is higher than the maximum number of expected connections.
The -Mn parameter multiplied by the -Ma parameter should be less than the value of the -n parameter.
( -Mn * -Ma < -n ).
