Hi Dirk,
I apologize for the long delay. My forum notifications got turned off by mistake.
An Unsupported MessageFormat error generally means that the log file is getting corrupted. Is the log file being written to mapped network drive? And is it being written to by CodeSite Dispatchers running on separate computers simultaneously?
Would you please send one of the bad log files to support@raize.com (zip it up) and I’ll take a look.
Ray
