ini_set('max_execution_time', 3);
while (true) {
  print '.'; flush();
  imap_append($mbox, "{}INBOX",file_get_contents('test.eml')) or die(print_r(imap_errors(),true));
  $object = imap_fetchstructure($mbox,1) or die(print_r(imap_errors(),true));
  imap_savebody($mbox,'/dev/null',1) or die(print_r(imap_errors(),true));
  imap_delete($mbox,1) or die(print_r(imap_errors(),true));
  imap_expunge($mbox) or die(print_r(imap_errors(),true));

Expected result:
clear exit

It is sadly not a PHP issue. c-client is horrible when it comes to error 
management (along other things) and it simply exit in some cases.

I would suggest to migrate your code to a PHP implementation for imap (roundcube's 
one is very good, zeta component too).
