Ignition service reboots itself

Sometimes Ignition Gateway reboots itself. How can i found the reason? Which log-files do you need to help?
Ignition 7.6.7 x32, Windows Server 2003 SP2

Assuming this is a Windows installation, you should navigate to the Ignition installation folder and open the \logs folder. Within the \logs folder, open wrapper.log. The restart reason is normally somewhere in the log. You may have to look in other files in the logs folder, such as wrapper.log.1.

Here are logs
Can you open this page and download?

There isn’t any obvious reason in the logs. The relevant portion is this:

INFO   | jvm 2    | 2016/05/17 09:44:47 | INFO  [SRContext                     ] [09:44:47,906]: Ignition["/main", state=RUNNING] ContextState = STOPPING
INFO   | jvm 2    | 2016/05/17 09:44:47 | INFO  [SRContext                     ] [09:44:47,906]: Ignition Gateway shutting down...
INFO   | jvm 2    | 2016/05/17 09:44:47 | INFO  [ModuleManager                 ] [09:44:47,921]: ModuleManager shutting down...

This indicates that a normal shutdown occurred. Maybe someone restarted the Ignition service?
