#31866 [Csd->Bgs]: IMAP extension

ID: 31866 Updated by: tony2001@php.net Reported By: aballai at gmail dot com -Status: Closed +Status: Bogus Bug Type: Performance problem Operating System: Linux PHP Version: 4.3.10 New Comment: Marking this report as bogus then. Previous Comments: ------------------------------------------------------------------------ [2005-02-09 23:08:32] aballai at gmail dot com This is unrelated to php and is related to c-client's ability to scale. Author of c-client will be contacted. ------------------------------------------------------------------------ [2005-02-07 03:01:55] rasmus@php.net 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. ------------------------------------------------------------------------ [2005-02-07 02:43:34] aballai at gmail dot com Description: ------------ 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++) { $mbox = imap_open("{localhost:143/imap/notls/novalidate-cert}INBOX", "user", "pass"); if(!$mbox) echo "failed ".$b++."\n"; } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31866&edit=1
