#47022 [Com]: Update of Bug 47000.

ID: 47022 Comment by: alan at binarystars dot com Reported By: alan at binarystars dot com Status: Feedback Bug Type: IMAP related Operating System: linux PHP Version: 5.2.8 New Comment: I'll try posting the URL again... the 't' is missing at the end of the line. http://home.binarystars.com/~alan/imap_bug/archive/method1_results.tx t Previous Comments: ------------------------------------------------------------------------ [2009-01-06 18:57:33] alan at binarystars dot com I assume you mean if I enable Zend Memory. If you check the Old test run where USE_ZEND_ALLOC=1 you can see PHP is cleared the memory successfully after an unset. http://home.binarystars.com/~alan/imap_bug/archive/method1_results.tx t However, the resident memory (RSS) remains high. Its almost like c- client keeps the email data in memory without flushing the memory. Again, this is a huge problem with systems that do not have a lot of free memory. Is there any way to flush the memory without exiting the script? ------------------------------------------------------------------------ [2009-01-06 17:55:22] scottmac@php.net Check memory_get_usage() to see what PHP is using, my guess is that there is a copy of the data in c-client and another for PHP. Immediately after that line has executed I'm assuming the c-client version is released. ------------------------------------------------------------------------ [2009-01-06 16:32:54] alan at binarystars dot com Description: ------------ Update of Bug 47000.
