The server is running Ubuntu Server 8.10 running Apache 2.2.11 compiled using (for testing purposes)
./configure --prefix=/usr/local/apache2 --with-included-aprI sent some traffic over from my other server to do a little testing, which is around 40 requests per second to static content and I seem to be getting a segfault for every request. Performance is very bad and it takes around 10 seconds to load.
Also, the worker MPM works fine with no errors and the performance is excellent.
The error log contains

[Thu Mar 19 23:41:31 2009] [notice] child pid 22410 exit signal Segmentation fault (11)I've done a memory check and everything appears to be ok.
The prefork Apache in the apt repo also seems to have this problem.
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>I have played with the settings although the segmentation faults always seem to occur on the prefork MPM.
