I have already reported this BUG at sf.net but for general Discussion I do it here again. I have a ISPc installation on an Ubuntu 7.04 Server. When I open the https://server:81/ Site in my Browser it hangs nearly every 2nd time at the ISP Manager. I also have Ubuntu 7.04 on my Client with Firefox 220.127.116.11. It works without any Problem under Windows. After a little while I get the possibility to stop the script. I've tried this at 2.2.14 and 2.2.15 and now at 2.2.16. It makes no difference if I use http or https.
