Host is blaming database time outs on Auto Blog Plug in. Any truth to this?

Lately I have been experiencing random database time outs that last up to a minute at a time, 2 or 3 times a day.

I'm on a dedicated plan, with probably 3 blogs running the auto blog plug in, importing maybe 10 feeds total anywhere from every 2 hours to one a day.

My host is telling me that the plug in is likely the culprit and I need to either not use it, or use another one.

Just wondering has anyone else experienced this, or is there a setting that I need to avoid to stop this from happening.
