[Xymon] dbcheck.pl goes purple for all monitored databases?

Before I look at spending a lot of time looking at the dbcheck.pl script, I thought I might ask if anyone else has seen the script hang when one of its queries does not return? Typically, dbcheck.pl -fast will hang on a query sent to a database that is having issues and so all the other monitored databases will eventually go purple as the dbcheck.pl is hung. Anybody else see the same issue and implement any solutions? I am going to look at the perl script and see if I can insert some timeout for any and all queries sent to the databases.
