ID: 41615 Updated by: tony2001@php.net Reported By: sms at inbox dot ru -Status: Open +Status: Feedback Bug Type: Unknown/Other Function Operating System: Windows 2000 SP4 PHP Version: 5.2.3 New Comment: Sorry, we can't fix something we can't reproduce. Previous Comments: ------------------------------------------------------------------------ [2007-06-07 08:07:00] sms at inbox dot ru I don't see a way to do it. I can't cut a part of a _huge_ board script. If it was a specific code construction I could do some tests and represent it here... I had PHP 5.2.2 running for ~32 hours and it generated more than 800 memory errors. My stats show ~40,000 hits for that period. So it doesn't fall over on every run. I also found a few errors like this: [26-May-2007 15:11:17] PHP Fatal error: Out of memory (allocated 7340032) (tried to allocate 160209 bytes) in Unknown on line 0 When I upgraded to PHP 5.2.3 I thought the problem is gone - it worked fine for the first 4 hours. And then it started all the same. As I remember PHP 5.2.1 fixed "Out of memory" bug that some people have in 5.2.0. So it's quite the contrary for me... ------------------------------------------------------------------------ [2007-06-06 22:41:32] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. Cannot reproduce. ------------------------------------------------------------------------ [2007-06-06 22:25:13] sms at inbox dot ru memory_limit is now set to 128M. PHP 5.2.0 works even with 16M though. ------------------------------------------------------------------------ [2007-06-06 22:13:54] tony2001@php.net What's the value of memory_limit? ------------------------------------------------------------------------ [2007-06-06 22:06:20] sms at inbox dot ru Description: ------------ I use binary zip package from php.net on Apache 2.2.4 (via php5apache2_2.dll). The problem: any version above 5.2.0 generates lots of "Out of memory" errors in random scripts (for example, Invision Board 2.1.7) and random source code constructions - I can't see any pattern. It was introduced in 5.2.1 and 5.2.2-5.2.3 didn't fix it. So I'm stuck with 5.2.0. The same php.ini was used. Tried bigger "memory_limit" with no luck... I included 4 lines of source code and 4 corresponding errors. Reproduce code: --------------- 1. function do_shutdown_insert( $tbl, $arr ) 2. $val = preg_replace( "/\\\$/" , "&#036;" , $val ); 3. foreach ($filter_keys as $k => $v) 4. if ( strstr( $result['location'], 'post' ) and $result['member_id'] != $this->ipsclass->member['id'] ) Expected result: ---------------- I expect no error as it was with 5.2.0 and below Actual result: -------------- and get this with 5.2.1-5.2.3: 1.
