I just did the update from Apache 1.3.28 and php 4.3.3 to Apache 1.3.29 and php 4.3.4 and I am now getting the seg faults with the Zend optimizer. I can remove Zend, but of course my Whois.cart will stop working, but everything else will work fin. I was not getting them with the previous versions. I am going to try a few things to figure out exactly which one of the updates is causing the problem. It worked fine before the update, so it has to be either apache, php or the frontpage stuff. If all else fails, I will just have to try and bring myself back to the version that worked.
