ID: 11676 Updated by: yohgaki Reported By: valerio@wnet.it Status: Open Bug Type: Scripting Engine problem Operating System: linux 2.4.5 i386 PHP Version: 4.0 Latest CVS (2001-06-25) New Comment: Could you try 4.1.0? see if it helps? Previous Comments: ------------------------------------------------------------------------ [2001-08-19 05:31:51] valerio@wnet.it There's only one issue... how can I determine which script was running on the processes that i find stuck? In the meanwhile i installed the Zend Optimizer on the server, and the problem seems to happen VERY less frequently... i know this is nearly no help at all, but I'm doing all I can. Anyway, i see some other guy had my same problem... ------------------------------------------------------------------------ [2001-08-19 04:56:56] sniper@php.net A short script that causes this would help a lot.. ------------------------------------------------------------------------ [2001-07-13 04:43:02] valerio@wnet.it anyone alive??? ------------------------------------------------------------------------ [2001-06-29 05:39:48] valerio@wnet.it Maybe this can help...i talked to the other guy who has the same problem than us , Denis (bug #11723), and we agreed that the problems began to arise after php 4.0.4pl1 (including it or not, we don't remember exactly :( ). Maybe this can help narrowing down the issue... ------------------------------------------------------------------------ [2001-06-28 15:21:12] valerio@wnet.it ok, i have recompiled php AND apache without any optimization settings, and things look worse... The problem happened more frequently in these hours, and these are backtraces of stuck processes: #0 0x4012c243 in chunk_free () #1 0x4012bfaa in __cfree () #2 0x810acbc in shutdown_memory_manager () #3 0x8079d58 in php_request_shutdown () #4 0x8077611 in php_apache_request_shutdown () #5 0x814a93e in run_cleanups () #6 0x814916d in ap_clear_pool () #7 0x81491e1 in ap_destroy_pool () #8 0x8158ded in child_main () #9 0x8158fdc in make_child () #10 0x8159089 in startup_children () #11 0x81596c6 in standalone_main () #12 0x8159e53 in main () #13 0x400ea9f3 in __libc_start_main () #0 0x4012c23e in chunk_free () #1 0x4012bfaa in __cfree () #2 0x810a5a5 in _efree () #3 0x811e8cc in zend_hash_destroy () #4 0x8112b7c in destroy_zend_class () #5 0x811ea67 in zend_hash_apply_deleter () #6 0x811ecfa in zend_hash_apply () #7 0x8110820 in shutdown_executor () #8 0x8119d53 in zend_deactivate () #9 0x8079d1a in php_request_shutdown () #10 0x8077611 in php_apache_request_shutdown () #11 0x814a93e in run_cleanups () #12 0x814916d in ap_clear_pool () #13 0x81491e1 in ap_destroy_pool () #14 0x8160eb2 in ap_destroy_sub_req () #15 0x8067cb8 in handle_include () #16 0x806acb5 in send_parsed_content () #17 0x806b28d in send_parsed_file () #18 0x814dc23 in ap_invoke_handler () #19 0x8161769 in process_request_internal () #20 0x8161b88 in ap_internal_redirect () #21 0x806b6dd in handle_dir () #22 0x814dc23 in ap_invoke_handler () #23 0x8161769 in process_request_internal () #24 0x81617cc in ap_process_request () #25 0x8158d9e in child_main () #26 0x8158fdc in make_child () #27 0x8159356 in perform_idle_server_maintenance () #28 0x8159895 in standalone_main () #29 0x8159e53 in main () #30 0x400ea9f3 in __libc_start_main () #0 0x4012c24b in chunk_free () #1 0x4012bfaa in __cfree () #2 0x810acbc in shutdown_memory_manager () #3 0x8079d58 in php_request_shutdown () #4 0x8077611 in php_apache_request_shutdown () #5 0x814a93e in run_cleanups () #6 0x814916d in ap_clear_pool () #7 0x81491e1 in ap_destroy_pool () #8 0x8160eb2 in ap_destroy_sub_req () #9 0x8067cb8 in handle_include () #10 0x806acb5 in send_parsed_content () #11 0x806b28d in send_parsed_file () #12 0x814dc23 in ap_invoke_handler () #13 0x8160e87 in ap_run_sub_req () #14 0x8067c35 in handle_include () #15 0x806acb5 in send_parsed_content () #16 0x806b28d in send_parsed_file () #17 0x814dc23 in ap_invoke_handler () #18 0x8161769 in process_request_internal () #19 0x8161b88 in ap_internal_redirect () #20 0x806b6dd in handle_dir () #21 0x814dc23 in ap_invoke_handler () #22 0x8161769 in process_request_internal () #23 0x81617cc in ap_process_request () #24 0x8158d9e in child_main () #25 0x8158fdc in make_child () #26 0x8159356 in perform_idle_server_maintenance () #27 0x8159895 in standalone_main () #28 0x8159e53 in main () #29 0x400ea9f3 in __libc_start_main () tell me what to do next and i'll gladly do it... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
