[users@httpd] Apache 2.2.x with Virtual IPs

[Pravesh Rai]

Hi All,

Observed that Apache 2.2.6 (& .15) throws exception inconsistently, at
different places, when the setup (Windows 2003 x86, with 4-12 GB RAM) is
configured with many Virtual IPs. This behavior differs on different setups.
On some setup, it fails even with 10-15 VIPs, but on the other, it fails
with more than 40 VIPs.

Here is the snapshot of Apache configuration:

---------

#MaxKeepAliveRequests 100
#KeepAliveTimeout 15

<IfModule worker.c>

</IfModule>
<IfModule perchild.c>

Do anybody has any clue on this ?

Thanks,
