![]() APAR status Closed as program error. Error description The Admin Server restarts the Application Server in a Windows environment. The tracefile reveals the following messages: ActiveServerP A ADMS0028I: Restarting server: ServerName ActiveServerP A ADMS0032I: Started server: ServerName (pid 2584) This is usually evidence that a process running under the JVM has crashed. Windows did not produce a DrWatson or user dump. Running an Admin Server trace reveals very litte as to why the Admin Server restarts the Application Server in this manner. For this case, it was determined that when the Admin Server restarted the JVM it did not attempt to shut down the Application Server JVM as it does when it receives a no ping received message. Instead it was determined that the Admin Service restarted the Application Server JVM due to Windows communicating to the AdminService that the JVM process has been terminated. There was some evidance that the JVM's resources were not totally released but this would require more investigation to be conclusive. If this is necessary then the WL3SM team would need to provide a diagonostic module to further investigate the Windows' issues. This APAR should provide a log message indicating why the Admin Server is restarting the Application Server. At this time the e-fix for this APAR has been put into the System Management cumulative efix which is: WAS_SysMgmt_01_07_2003_4.02_4.03_4.04_AE_cumulative_Windows_eFixLocal fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server users. * **************************************************************** * PROBLEM DESCRIPTION: User sees application server being * * restarted by admin server without * * any explanation. * **************************************************************** * RECOMMENDATION: * **************************************************************** The admin server will restart an application server if: 1) The application server fails to send a "ping" to the admin server. In this case, the admin server will try to gracefully shutdown the application server before restarting it. There will be log entries in this scenario. 2) The application server process terminates unexpectedly. This is what was occurring in this scenario.Problem conclusion Code to produce log entries was added to report that the application server has terminated and the exit code from the application server is also reported.Temporary fix Test fix sent to Harry Rumley.Comments
