Description: ------------ We are using Apache 2.0.53 as intranet server and proxy server. When loading PHP 5.0.4 as Apache module, some Apache childs, after few minutes, randomly, and take 100% cpu load. This also occurs with PHP 4.3.10 and other PHP 5.0.X libraries. This appears even while only using proxy without intranet PHP pages. Tracing this processes with strace give nothing. (No syscalls) Here, results of backtrace Actual result: -------------- (gdb) bt full #0 0x406e993f in execute (op_array=0x824de24) at /root/sources/php- 5.0.4/Zend/zend_execute.c:1406 execute_data = {opline = 0x825f2a4, function_state = {function_symbol_table = 0x140, function = 0x824de24, reserved = {0x403e0d24, 0x403e0d05, 0x82554e4, 0x824ddf4}}, fbc = 0x0, fbc_constructor = 0x406a98e0, op_array = 0x824de24, object = 0x0, Ts = 0xbfffc190, original_in_execution = 1 '\001', calling_scope = 0xbfffd300, prev_execute_data = 0xbfffd300} #1 0x406ee195 in zend_include_or_eval_handler (execute_data=0xbfffd300, opline=0x82520b8, op_array=0x825f2a4) at /root/sources/php-5.0.4/Zend/zend_execute.c:3581 new_op_array = (zend_op_array *) 0x824de24 original_return_value = (zval **) 0xbfffd37c inc_filename = (zval *) 0x0 tmp_inc_filename = {value = {lval = 136633720, dval = 2.1895018180807644e-314, str = {val = 0x824dd78 "?d%\b@x%\b\005", len = 1}, ht = 0x824dd78, obj = {handle = 136633720, handlers = 0x1}}, refcount = 0, type = 172 '?', is_ref = 223 '?'} failure_retval = 0 '\0' #2 0x406e9942 in execute (op_array=0x824dcf4) at /root/sources/php- 5.0.4/Zend/zend_execute.c:1406 execute_data = {opline = 0x82520b8, function_state = {function_symbol_table = 0xbffff630, function = 0x824de24, reserved = {0x0, 0x0, 0x0, 0x0}}, fbc = 0x0, fbc_constructor = 0xbffff630, op_array = 0x824dcf4, object = 0x0, Ts = 0xbfffd2e0, original_in_execution = 0 '\0', calling_scope = 0xbffff630, prev_execute_data = 0x0} #3 0x406cd08b in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /root/sources/php-5.0.4/Zend/zend.c:1069 files = 0xbfffd434 "" i = 1 file_handle = (zend_file_handle *) 0xbffff630 orig_op_array = (zend_op_array *) 0x0 local_retval = (zval *) 0x0 #4 0x4069c3b8 in php_execute_script (primary_file=0xbffff630) at /root/sources/php-5.0.4/main/main.c:1632 prepend_file_p = (zend_file_handle *) 0x0 append_file_p = (zend_file_handle *) 0xbffff630 prepend_file = {type = 0 '\0', filename = 0x0, opened_path = 0x0, handle = {fd = 0, fp = 0x0, stream = {handle = 0x0, reader = 0, closer = 0, interactive = 0}}, free_filename = 0 '\0'} append_file = {type = 0 '\0', filename = 0x0, opened_path = 0x0, handle = {fd = 0, fp = 0x0, stream = {handle = 0x0, reader = 0, closer = 0, interactive = 0}}, free_filename = 0 '\0'} old_cwd = 0xbfffd440 "/" old_primary_file_path = 0x0 retval = 0 #5 0x406f3320 in php_handler (r=0x8239e28) at /root/sources/php- 5.0.4/sapi/apache2handler/sapi_apache2.c:555 ctx = (php_struct *) 0x8241e58 brigade = (apr_bucket_brigade *) 0x8241ed0 bucket = (apr_bucket *) 0x825f2a4 rv = 136704676 parent_req = (request_rec *) 0x0 #6 0x08067c06 in ap_run_handler (r=0x8239e28) at config.c:153 pHook = (ap_LINK_handler_t *) 0x825f2a4 n = 10 rv = 136704676 #7 0x080681d8 in ap_invoke_handler (r=0x8239e28) at config.c:364 handler = 0x8142cf8 "application/x-httpd-php" result = 136583672 old_handler = 0x0 #8 0x08065696 in ap_internal_redirect (new_uri=0x81430c8 "/error.php3?
