I have the following problems with all of my sites, both
on XOOPS 1.3.x and 2.0.x. Have ran it on different PC's
with different O\S with the same results.

EVERYTHING works perfect, but after opening about 20-30 different
threads in the NewBB Forum i stops working. After that
i can't access, edit or post in ANY threads! I klick a
thread and the timeglass shows until i get a timeout...
When this happends i delete the xxx@newbb[x].txt cookie
and everything works fine again!!

This is no big problem for me, but my users just can't
stand this as many have little PC knowledge :)

The sites are running on Windows 2003 server with 2 Ghz
CPU and 1024Mb Ram. I'm also behind a D-Link 604i firewall.
Xoops is running under the following config:

+ Apache 2.0.48
+ MySQL 4.0.15
+ PHP 4.3.4 + PEAR
+ Perl 5.8.0

register_globals = On

Thankful for any ideas...
