Hello, I installed httpd 2.4.2 on CentOS6.2(64bit). It seems like httpd leaks memory when mod_ssl is used. When I start up httpd with mod_ssl, and when I issue "apachectl graceful", it seems like httpd leaks memory. If I issue "apachectl graceful" 1000 times, ps command shows the memory usage gets bigger like below: ====Before 1000 times graceful restart==== # ps -elfy | head -1 S UID PID PPID C PRI NI RSS SZ WCHAN STIME TTY TIME CMD # ps -elfy | grep httpd | grep -v grep S root 3816 1 0 80 0 4136 25683 poll_s 15:00 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 3818 3816 0 80 0 5216 111748 pipe_w 15:00 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 3819 3816 0 80 0 5220 111748 pipe_w 15:00 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 3820 3816 0 80 0 5220 111748 pipe_w 15:00 ? 00:00:00 /opt/testhttpd/bin/httpd # ====After 1000 times graceful restart==== # ps -elfy | head -1 S UID PID PPID C PRI NI RSS SZ WCHAN STIME TTY TIME CMD # ps -elfy | grep httpd | grep -v grep S root 3816 1 6 80 0 97320 48673 poll_s 15:00 ? 00:01:23 /opt/testhttpd/bin/httpd S daemon 28584 3816 0 80 0 97448 134738 pipe_w 15:19 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 28585 3816 0 80 0 95416 134738 pipe_w 15:19 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 28588 3816 0 80 0 97460 134738 pipe_w 15:19 ? 00:00:00 /opt/testhttpd/bin/httpd # You can reproduce this by: 1. start httpd with mod_ssl loaded. 2. issue "apachectl graceful" 1000 times. I configured my httpd with following: # ./configure --prefix=/opt/testhttpd --with-included-apr If I start up httpd without mod_ssl, memory usage does not get bigger even after 1000 times graceful restart. The evidence is below: ====Before 1000 times graceful restart==== # ps -elfy | head -1 S UID PID PPID C PRI NI RSS SZ WCHAN STIME TTY TIME CMD # ps -elfy | grep httpd | grep -v grep S root 25061 1 0 80 0 2632 18365 poll_s 15:43 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 25063 25061 0 80 0 4504 104430 pipe_w 15:43 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 25064 25061 0 80 0 4504 104430 pipe_w 15:43 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 25065 25061 0 80 0 4508 104430 pipe_w 15:43 ? 00:00:00 /opt/testhttpd/bin/httpd # ====After 1000 times graceful restart==== # ps -elfy | head -1 S UID PID PPID C PRI NI RSS SZ WCHAN STIME TTY TIME CMD # ps -elfy | grep httpd | grep -v grep S daemon 17566 25061 0 80 0 4784 104430 pipe_w 16:01 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 17567 25061 0 80 0 4788 104430 pipe_w 16:01 ? 00:00:00 /opt/testhttpd/bin/httpd S daemon 17568 25061 0 80 0 4792 104430 pipe_w 16:01 ? 00:00:00 /opt/testhttpd/bin/httpd S root 25061 1 0 80 0 3264 18365 poll_s 15:43 ? 00:00:06 /opt/testhttpd/bin/httpd # Are there memory leaks in mod_ssl module?
