Since upgrading to ZEN 11.3.0 and then applying the FTF Roll Up for ZENworks (11 SP3) update, I am now getting, about every two days or so, notice that I cannot make changes as the zenworks-myzone log file is FULL.

I then have to run a log backup before I can make any changes in the ZCM.

I am running MS SQL 2008 R2 and the database is in FULL recovery mode, so a full backup isn't truncating the log file at all. The data file is about 38GB while the transaction log is about 220GB!
Is FULL recovery mode required or could we use SIMPLE so the log will truncate during a full backup?
