Greetings, We had an old 2.0.x otrs setup running relatively smoothly (if slow since the DB was huge) with PostgreSQL for many years. The decision was made to switch to MySQL and start afresh with the latest otrs - the idea being to be as standard as possible to avoid problems, etc. Anywho, most things seem fine and dandy, except random SQL problems when replying/adding notes/etc. The error will typically be something like: ------------------------------------ Error: MySQL server has gone away, SQL: 'INSERT INTO article_plain (article_[..] Traceback: ERROR: OTRS-CGI-22 Perl: 5.8.8 OS: linux Time: Fri Apr 23 10:32:32 2010 Message: MySQL server has gone away, SQL: 'INSERT INTO article_plain (article_id, body, create_time, create_by, change_time, change_by) VALUES (?, ?, current_timestamp, ?, current_timestamp, ?)'

Does anyone know what the hell this is all about? Alternatively, please direct me to the relevant log files which might help me figure out what I've done wrong. Thanks Henry
