Hi, a few days I noticed that our otrs-system is very slow. But only when I browse through the queues, every other page is as fast as usual, so I thought, the problem is somewhere else. I just realized, that everytime someone clicks on "Queue View" or any queue the load on the Server jumps at 100% running 'postmaster' for about 5 seconds, then the queue is displayed and the server load is at zero. now I found in apache errorlog: Charset encode 'unicode-1-1-utf-7' -=> 'iso-8859-15' (postmaster@digitalworkshop.com) not supported! Charset encode 'unicode-1-1-utf-7' -=> 'iso-8859-15' (rz.ca@uni-konstanz.de) not supported!
