Potential Apache issues due to Zend Optimizer v3.0.0

Just had a problem on a clients server which took a while to track down.Symptoms: If you rebuild apache/php and find that httpd appears to hang without spawning any children and nothing in the error log, this could be the problem. Using an strace on httpd -X shows the binary hanging on apache module loads.I finally tracked this down to Zend Optimizer v3.0.0 which is available in the current EDGE/CURRENT releases of cPanel ( 10.8.2-EDGE_41) in /scripts/installzendopt. Trick is to edit the script and set:

my $ver = ‘2.6.2’;

Then rerun the script and restart httpd. Hopefully this will help anyone who finds themselves with the same issue.

Why you should use :fail: – addendum

I have added the following to the Why you should use :fail: page on our site:

Causes emails that will never be delivered onto the exim mail queue because checks such as sender verification are still carried out when processing such emails and if they cannot complete they will stay on the exim mail queue and repeatedly reprocess the email until it is finally discarded (usually 4+ days). This can cause very large mail queues full of spam which is repeatedly processed causing severe performance degradation
