SMTP Email weirdness

Posts: 43
I have a Netlinx system that, among other functions, serves as a master monitor for several interconnected paging systems, each of which have their own Netlinx master connected via M2M, and recently added email functionality that sends status updates to a list of addresses stored in an array. The message format is simple, listing the time & date the master sent the message, then text describing the status of each system on the network, followed by a bit of text explaining why the email was sent (system showing alarm, warning, status change, or user interaction).
This is triggered by a timeline that fires every 6 hours, plus any time status changes of one of the systems, or when an admin manually sends a test email from a virtual TP.
Everything works OK, except at the end of each email, there is sometimes a bunch of random junk appended, which looks like part of a previous email. I can't nail down why this would happen, as the message is assembled in a STACK_VAR inside the function that sends the email.
Has anyone had any experience with this? Master is running FW v4.1.373, code for email functionality is below:
Thanks,
