We have some problems with some GP tools that uses multi processing, mainly the cache commands Export Tile Cache and Manage Tile cache.
When you check the task manager when these tools run you see that ArcMap.exe create a ARCSOMP.exe process, then a few ARCSOCP.exe processes created (the number of processes is by the multi processor env setting). These ARCSOCP.exe command really get the CPU and do the work.
On Some machine, some times I see the ARCSOMP.exe starts and no ARCSOCP.exe, after a few seconds I get 99999 error and the message is Configuration of RasterCommander.ImageServer can not be added.
Some time I can close ArcMap, reopen, do the same tool and it works. Some time I have to restart ArcMap a few times before it is running successfully again. I found no errors in the event viewer.
This happens on a few different machines in our office. We use ArcMap 10.3
Anybody have any idea?
