CAUSE:
Bug# 20020403-022
CAUSE:
This is a bug in broker. The problem was caused by a small timing window opened up when starting the minimum number of agents. The server threads were incorrectly started in the READY state. This caused the connect request to be issued to the server thread before it was ready, resulting in the FSM error.
FIX:
This issue has been fixed in the following Progress 9.1C patches and 9.1D.
