	The ones above would be possible given certain network configurations (i.e. slow WAN link to remote site, etc). They could also indicate that the host or service you are checking is down. You should be able to determine the cause through troubleshooting...

	Yes, but requires code editing. Search for the exit strings in the source of the plugin or within nagios and change the exit or state code to 2. Bear in mind that these could also indicate other problem with the services you are checking.

You might also consider increasing your retry count instead so that you give more time for temporary latency issues and the like to resolve themselves.
