Status: Verified
SYMPTOM(s):
Error <errMsg> ... disconnecting client. (8091)
Connection failure for host <host_name> port <port> transport <transport_name>. (9407)
Application Server Shutdown. (5476)
Transport resources unavailable. (5486)
AppServer client gets disconnected with error 8091
Error does not happen when Fathom for Management is not installed
FACT(s) (Environment):
Progress 9.1D
Fathom for Management 2.1A
CAUSE:
Bug# 20030610-043
CAUSE:
The bug was caused by the introduction of the PROCSTATS message sent by the AppServer to the broker to collect statistical information for Fathom. The result was that under certain timing conditions, the broker incorrectly assigned the same AppServer to two different clients concurrently.
FIX:
Upgrade to 9.1D09 or 10.0B.
If an upgrade is not possible, the following workaround is available:
Add the following line for either the UBroker.AS setting or for each AppServer Broker in the ubroker.properties file.
collectStatsData=0
In order to have the AppServer Brokers make use of this property, the AppServer Brokers will need to be restarted.
