Thanks for responding and confirming. We have a few thousand desktops with deployed MBARW business 0.9.17.689 and have logged ~150 occurrences of temp profiles, mostly 1-2 per machine. We cannot reproduce the issue at will. Do you have an updated business version of the software available to us?
On a side note, we are interested in some more details on another issue resolved in BETA 9 - improved memory consumption. We have seen 20+ cases, on different machines, where all available memory (I remember instances with 9GB+ private memory set) and all CPU cycles (especially on machines with 4 cores or less) are consumed by MB3Service.exe.
