Bug #12583: Some children get stuck and consume all CPU time (bug #11676?)

From: swan@multiplayer.it Operating system: Linux 2.4.7 PHP version: 4.0.6 PHP Bug Type: Scripting Engine problem Bug description: Some children get stuck and consume all CPU time (bug #11676?) After some unexplainable crash of our webserver, i managed tracking down some children who had incredibly high running time (in the order of hundreds of minutes!) and CPU consumption... I backtraced 2 of 'em and this is what i got: #0 0x4012c248 in chunk_free () #1 0x4012bfaa in __cfree () #2 0x8109741 in zend_hash_destroy () #3 0x807bc95 in php_shutdown_config () #4 0x80799a0 in php_config_ini_shutdown () #5 0x8079e85 in php_module_shutdown () #6 0x8079e58 in php_module_shutdown_wrapper () #7 0x8077c45 in php_child_exit_handler () #8 0x814af41 in ap_child_exit_modules () #9 0x8150c5d in clean_child_exit () #10 0x8153a87 in child_main () #11 0x81540ac in make_child () #12 0x8154426 in perform_idle_server_maintenance () #13 0x8154965 in standalone_main () #14 0x8154f23 in main () #15 0x400ea9f3 in __libc_start_main () #0 0x4012c243 in chunk_free () #1 0x4012bfaa in __cfree () #2 0x80f5b4c in shutdown_memory_manager () #3 0x8079978 in php_request_shutdown () #4 0x8077291 in php_apache_request_shutdown () #5 0x8145a0e in run_cleanups () #6 0x814423d in ap_clear_pool () #7 0x81442b1 in ap_destroy_pool () #8 0x8153ebd in child_main () #9 0x81540ac in make_child () #10 0x8154426 in perform_idle_server_maintenance () #11 0x8154965 in standalone_main () #12 0x8154f23 in main () #13 0x400ea9f3 in __libc_start_main () I searched through the bug reports and it looks exactly like bug #11676 adn probably #11723, but that bug has not been solved, or at least it looks so... We're running php 4.0.6(+memory limit fix) on apache 1.3.20 on a linux 2.4.7 with glibc 2.1.3-6 (caldera eserver 2.3). My conf line was: CFLAGS="" \ ./configure \ --with-apache=../apache_1.3.20 \ --with-mysql \ --enable-memory-limit Let me know if I have to do something to help you more.
