hi, maybe someone of you guys will help me on this case, as i did a search on the whole internet and could spot anyone having the same problem as i have. well, since we use OTRS on a productive manner i can find over and over again this kind of error in the logs: [Tue Jun 23 16:39:17 2009][Error][Kernel::System::User::GetUserData][164] No SCALAR param in Bind! well, actually everything works pretty good... however we experience sometimes some strange DB behaviour that could only be resolved with a restart of the OTRS/apache service... and since i figured out, that this "no scalar param in bind" can be found in the DB.pm file, i am not sure if there is maybe a coincidence... here is our system overview: windows 2003 mssql 2008 apache 2.2.10 perl 5.10.0.1004 mod_perl 2.0.4 otrs 2.3.4 thanks a lot for every hint that might solve this issue. regards, patrick.
