[Xymon] Bug with Xymon Client Data Parsing?

I posted a related message a couple weeks back. We continue to see periodic issues with hobbit tests having a problem parsing certain strings. I don't know if its happening on only things we've setup a regex to look for, or if those are just the ones we notice. I suspect both, as sometimes the client data received via the xymon server is garbled, and sometimes its clean.
I've seen this in the following tests: disk cpu procs
See below for an example of garbled data
368 tr]debot 21:27:22 S 19 0.0 00:00:00 0.
However, when I click on the client data link on the webpage, to see what xymon is parsing, I see the following:
9375 tradebot 20 0 24556 5424 1720 S 0 0.0 0:00.17 bash
So I've seen scenarios where the client data looks ok, as in above, and when the client data looks garbled.
When last I posted, the suggested fixes involved increasing the values of MAXLINE, MAXMSG_STATUS, MAXMSG_CLIENT, and MAXMSG_DATA in hobbitserver.cfg, but I had already increased those much beyond the defaults due to previous truncation issues. We've got a few clients sending some very long PROCS and CPU messages.
The xymon logs don't show anything. We are running Xymon 4.3.0-0.beta2
Is this a known bug with regex parsing?
