Hi!

After the performance problems I encountered on one of my machines, I 
downgraded to 1.8.2.2 again (since then, the server runs flawless again) and 
wanted to try it on another machine, unfortunately with even less luck, and 
lots of segfaults instead. So I installed the 1.8.4 snapshot, which segfaults 
a little bit less, but still every second time I load a page in spider-admin:

Program received signal SIGSEGV, Segmentation fault.

When I try acessing a midcom-2.6 host, I get the following (every time):

Program received signal SIGSEGV, Segmentation fault.

As usual, I'd be most grateful if someone could give me a hint what went wrong 
here.


Bye,

Andreas
