I can't reproduce this. Previous Comments: ------------------------------------------------------------------------ [2003-07-10 18:14:41] jordan at tumyeto dot net Description: ------------ Summary: If the directory containing error_log is not writeable, Apache gets stuck taking 100% CPU. Detail: I recently set log_errors = On in php.ini, and began receiving a TON of "[notice] child pid 15591 exit signal Segmentation fault (11)" in my Apache error_log. In addition, a ton of "Allowed memory size of 8388608 bytes exhausted (tried to allocate 2 bytes)" began showing up as well. Even worse, Apache child threads would shoot up to 100% CPU and over time 5-6 threads would all be fighting for that 100%, causing page serve problems. I come to find out that the directoy that error_log was set to go to was not writeable by the webserver user. As soon as I make the directory writeable (or turn off log_errors), all problems go away and the server returns to normal operations.

Expected result: ---------------- If error_log cannot be written, abort instead of taking down Apache. Actual result: -------------- [notice] child pid 15591 exit signal Segmentation fault (11) Allowed memory size of 8388608 bytes exhausted (tried to allocate 2 bytes) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24597&edit=1
