Previous Comments: ------------------------------------------------------------------------ [2002-02-04 02:20:39] yohgaki@php.net The version of PHP that this bug was reported in is too old. Please try to reproduce this bug in the latest version of PHP (available from http://www.php.net/downloads.php If you are still able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". ------------------------------------------------------------------------ [2001-12-11 09:51:44] dshadow@zort.net I tried using apache_child_terminate() as suggested, however, this doesn't help any. (It might be beneficial if this function and its required configuration option were documented somewhere.) ------------------------------------------------------------------------ [2001-12-10 22:32:39] zak@php.net Could you try calling apache_child_terminate() at the end of your script? ------------------------------------------------------------------------ [2001-12-04 10:54:55] dshadow@zort.net This helps with my problem of apache children being left in unusable states with large memory allocations. However, it is still entirely unreasonable that memory that takes only a few seconds to allocate should need several minutes to be disposed of. I just watched PHP take *six* minutes to dispose of 70 megs of memory it allocated, and on prior occasions when no one was watching, I've found it to have be running for *hours* cleaning up after itself. ------------------------------------------------------------------------ [2001-12-03 17:46:34] venaas@php.net I've seen this as well. The time limit you set is removed when the script finishes but before the memory is cleaned up. What I did to avoid the problem was to change the code in php_request_shutdown() main/main.c. The end of the function looks like: zend_try { shutdown_memory_manager(CG(unclean_shutdown), 0); } zend_end_try(); zend_try { zend_unset_timeout(TSRMLS_C); } zend_end_try(); I switched the timeout and the shutdown, and then it worked for me. It still takes a long time, but you don't get a timeout. Not sure if this is the correct fix, but maybe you want to test and confirm that it helps? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
