[mapguide-users] mgservice at 100%

Mon Mar 19 19:58:31 EDT 2007

Hi George,

I suggest you to perform a "cold" backup then a restore of the
repositories. The instruction should be under the MapGuide Server
installation directory:

	..\Server\RepositoryAdmin\RepositoryAdmin.pdf

Subject: [mapguide-users] mgservice at 100%

I am having problems with mgserver.exe running at 100% in Windows XP.

I tried repair of mgserver and extensions but that did not solve it so I

uninstalled extensions and server then reinstalled. This did not solve 
the problem either.

I found the discussion below and have stopped the service in task 
manager and tried running as an application from the command line using 
'mgserver run'. After starting as an application my CPU is still pegged 
at 100% with mgserver.exe as the process using all the CPU

Before re-installing I made copy of all the files and folders under the 
C:\Program Files\MapGuideOpenSource folder so I am assuming I have 
everything backed up.

Should I uninstall and then delete all the repositories etc then 
re-install? Any other suggestions?

Thanks

George
