IMAP extension does not handle 150+ simultaneous transactions.  Random connections to IMAP are dropped.

Run the code below in multiple processes simultaneously to see connections dropped.  

This performance issue is seen in enterprise webmail systems.  Unless caching is used, which it always should, connections will be dropped.

Reproduce code:
$b =0;
for( $a = 0; $a< 100; $a++)
$mbox = imap_open("{localhost:143/imap/notls/novalidate-cert}INBOX", "user", "pass");
        echo "failed ".$b++."\n";

Write a little C program against the cclient libary that does the same and see if you have the same problem.  If so, report it to the cclient author.  If not, we will have a look.  On the surface I doubt this is a PHP issue.

This is unrelated to php and is related to c-client's ability to scale.  Author of c-client will be contacted.

Marking this report as bogus then.
