Redmine

Hello,

we recognized some strange error messages in our logs, that look like perl's mysql connection library problems, maybe version conflicts or multi threading problems, but we are using debian lenny stable packages. I read that using perl in multi threading isn't advised for production, but the perl package "...linux-gnu-thread-multi" (look like the multi threading package) came with the debian standard packaging. All packages are apt-get uptodate to lenny repositories, we did an dist upgrade and installed vmwatetool (driving on exi) some days ago.

Following the error messages and files snipets with the code pointed in the error messages.
Would be great if some can give some hints, what could be the cause.
