Hi, Eric, I'm sorry for the disturbing for this problem.
I used GDB to trace the code, in the hope of understanding why httpd never print that log message. Basically, that following code print out the log message: /* server/mpm/event/event.c */ 3182 ap_log_error(APLOG_MARK, APLOG_INFO, 0, NULL, APLOGNO(00521) 3183 "MaxClients is deprecated, use MaxRequestWorkers " 3184 "instead."); and at the startup, the system did execute this logging statement. but when go inside the ap_log_error function, it fails into the following if condition: /* server/log.c */ 1120 /* 1121 * If we are doing stderr logging (startup), don't log messages that are 1122 * above the default server log level unless it is a startup/shutdown 1123 * notice 1124 */ 1125 #ifndef DEBUG 1126 if ((level_and_mask != APLOG_NOTICE) 1127 && (level_and_mask > ap_default_loglevel)) { 1128 return; 1129 } 1130 #endif Here, level_and_mask is 6 (APLOG_INFO), and ap_default_loglevel is 4. So the code simply returned without printing the log message, and that's why I never had chance to see the log message. I have the following two questions: 1. How to enable the DEBUG macro in this case? 2. Is this behavior on purpose? because I think most httpd are not enabled with DEBUG, so this kind of information is hardly to be noticed.
