Full text catalog is paused

I have 2 full text catalogs, and one of them (sometimes both) goes to pause
status occasionally. I suspect this occurs during a backup.
I checked the status of the Microsoft search service and it states that it
is "started", but I've found that restarting the service unpauses the
catalog.
This is an improvement on my previous solution of rebuilding the catalog...
Any ideas what may be causing the pausing?
Or failing that, how can I issue a restart command to the service?
I have VB6 apps running that can detect the paused catalog, so restarting
would be simple if I knew how.
TIA

I should have mentioned that the error from the event log when the pausing
occurs is:
