PQ72896: DRSOCKET CAUSES LOGS TO FILL UP ON STOPPING NODE

 A fix is available

4.0.7: WebSphere Application Server Version 4.0 Fix Pack 7



APAR status
Closed as program error.

Error description
The stderr logs are bing filled with the message
DRadminserver I failed to read stop bytes. This appears to be a
loop in DrSocket.java where a call is made to stop the node. The
code checks a vector passed in for 4 bytes and verifys these 4
bytes are "S" "T" "O" "P".  SInce we are shutting the system
down anyway, we should just print out what the vector args are,
if not stop or < or > 4 and conitnue with the shutdown.

****************************************************************
If a customer uses the Windows Services to stop a Node, the
customer may see the stderr logs filled with the message
"DrAdminserver failed to read stop bytes".  The logs fill up
and may eventually put the system to a halt.
Problem conclusion
DrSocket explicitly listens and checks for incoming "S" "T"
"O" "P" bytes from Windows Services to stop the node.
Since this code is only executed during system shutdown, the
current check is redundant.
With this fix, DrSocket accepts the incoming bytes,
prints out what the vector args are, and proceeds with the
shutdown.
Temporary fix
