Occasional watchdog timeouts on netcams


I have motion setup to monitor a bunch (18) of network cameras. Occasionally a thread dies with a watchdog timeout. Unfortunately this causes all the viewers watching the motion feeds to stop so this is a significant hassle. Any ideas why this is happening and what can be done to prevent it?

The webcams are various Axis models.

I don't believe this is caused by loss of connectivity. When I see loss of connectivity I get a "Video signal lost - Adding grey image" message which does not cause problems with the viewers.
Errors logged are:
