Explanation: The dbstop.exe utility was unable to stop the Foxhound database, possibly because it was originally started via the network server dbsrv11.exe without -gk all being specified on the command line.

This problem can affect the post-setup stage of a Foxhound installation, as well as the following Foxhound shortcuts:

All Programs - Foxhound1 - Tools - Start Foxhound via Firefox - debug

All Programs - Foxhound1 - Tools - Start Foxhound via IE - debug

All Programs - Foxhound1 - Tools - Stop Foxhound Engine

Here's a sample of this error message from the post_setup_trace.txt file:
