The use of Windows XP as an operating system  for FLEXlm license servers is very popular in organizations. It allows the reuse of existing OS licenses and provides the needed functionality.

OpenLM Broker is an optional but highly recommended component that can be installed on the license server. It supports any operating system that supports JAVA. On Windows it’s implemented as a service. The OpenLM Broker provides advanced functionality to FLEXlm and other supported license managers such as IBM LUM, Sentinel RMS, Sentinal HASP and others.

When logging out of Windows XP the operating system it sends the SIGHUP signal. The SUN JVM interprets it as a shut down command and closes the java.exe process that serves OpenLM broker.

This behavior on Windows XP  is causes the Java process to die away when the user is logging out of the XP based license server.

The solution is simple, add the -Xrs flag to the the Broker startup command.

open the registry editor,
go to key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\OpenLM Broker\Parameters
modify the “Application” value to :
“C:/Program Files/Java/jre6/bin/java.exe” -Xrs -jar “C:\Program Files\OpenLM\OpenLM Broker/OpenLMBroker.jar”  start “C:\Program Files\OpenLM\OpenLM Broker/broker.xml”

This issue is solved in version of OpenLM Broker.
