We had this issue as well. Our setup is very similar to yours. My understanding was this is fixed in 6.6.1 so I upgraded over the weekend. So far I have not had any reports of crashing since. We did run into issue with where we are getting the following message on 3 or 4 meds: "Cannot Transmit prescription because: metoprolol tartate 50 mg oral tablet: This drug does not have an NDC."
Apparently is is bug with 6.6.1 and being worked on.
