Hi guys, looking at the file Error.log of Apache I find this error cyclically
[Tue Mar 19 15:36:09 2013] -e: DBD::mysql::st fetchrow_array failed: fetch() without execute() at C:/PROGRA~1/OTRS/OTRS//Kernel/System/DB.pm line 616
Scalar leaked: 1
Do you know why?

We have an OTRS 3.0.10 on Windows Server 2003 from about 6 months with 200 Tickets per day and  we are having a gradual degradation in performance.

Thanks
Rocco
