Answer: Messages like this appearing in Foxhound Options - Display Diagnostics mean that the Foxhound Monitor has given up waiting for a "connection failed" response to its attempt to connect to the target database:

   1663 2010-06-13 06:58:13.796 Full Build 3700a 1000000035 202a3a(202eh1) 
   Connection timeout for target DSN xxx after 15.1s (timeout threshold is 15.0s; see Foxhound Options) - 1000002348

Note that Foxhound does not give up trying to connect just because a connection failed, that's not what this kind of "timeout" is; for more information see Foxhound Options - Connection Timeout.

To stop further attempts to restart start sampling for this target database after a timeout, click on Start Sampling, then Cancel Request.

To stop all further attempts to restart sampling after a time out, or to change how often the attempts are made, see Foxhound Options - Timeout Retry.
