| Problem | You do not know why the application server restarts, and you notice the following entry in the tracefile:
[02.08.23 02:02:53:567 EDT] 876dc41c ActiveServerP A ADMS0028I: Restarting server: "Internet" | | | | Solution | An application server restarts because of the Ping Timeout or because the process crashed. This document describes how to determine why the application server has been restarted.
If it is determined that the application server crashed, see the links under the Related information section below for the document that pertains to your operating system.If it is determined that the application server was restarted because of a Ping Timeout, see the link under the Related information section below.- Ping Timeout:
- If you are running WebSphere® Application Server version 3.5.5 and higher or any release of version 4.0, the "Restarting server" message will be preceded by the following line:
[02.08.23 02:02:53:567 EDT] 876dc41c ActiveServerP A No Ping Received - Stopping server: "Internet"
- If you are running WebSphere Application Server version 3.5.4 or lower, the "Restarting server" message will NOT be preceded by the "No Ping Received" message. You will then need to determine if application server crashed. If there is no evidence of a crash, then it most likely restarted due to the ping timeout. Follow section B below to determine if the application server crashed. If there is no evidence of a crash, see the link for a restart due to a Ping Timeout under the Related information section below.
- How to determine if the application server crashed:
- For AIX®:
Run the following command to determine if a process crashed on AIX:
errpt -a >errpt.out
The following is sample output from the errpt.out file. The process ID can then be compared to the PIDs in the tracefile.

- For Solaris™:
To determine if the process crashed, check the /var/adm directory for a file named "messages".
- Windows®
To determine if the process crashed, check the drwtsn32.log file for the PID of the Application Server. The default location is the \Winnt\System32 directory on Windows NT 4.0 and \Documents and Settings\All Users\Documents\DrWatson on Windows 2000.
Following is sample output from drwtsn32.log:
