I use the "Squirrel Mail v1.4.5" as my web mail system under the Apache 1.3.34 + PHP 4.4.0 structure. It is working normally.

After I upgrade the PHP to version 4.4.1, I can't read the mail. The mail reading program was executing timeout. When the program was running, the CPU loading was 100%.

The following is my configure parameters :
./configure \
--prefix=/usr/local \
--with-apxs=/apps/apache/bin/apxs \
