Hello, I'm currently using Apache 2.2 under Debian Etch, with FastCGI/Suexec and Php5.2 (all of these softwares have been installed as Debian paquets, using aptitude). The server is a Pentium 4 (3 Ghz) with 2 Gb of RAM. It serves a lot of requests (about 30 to 35 per second, mainly weblogs and forums). This server is only used to run Apache and Proftpd. I recently switched from Apache 1.3 to Apache 2.2, from php4 to php5 and from Debian Sarge to Debian Etch (from scratch). Since this major update I am running into memory consumption problems with Apache 2 : CPU load is correct, however memory consumption is really high : some Apache 2 processes can take up to 10 % of total RAM, which is more or less equal to 200 Mb : 15641 www-data 20 0 31416 16m 864 S 1 0.8 1:32.64apache2 3673 www-data 20 0 422m 114m 2416 S 0 5.7 0:10.87apache2 4364 www-data 20 0 408m 107m 3076 S 0 5.3 0:10.12apache2 5771 www-data 20 0 599m 207m 2028 S 0 10.3 0:20.58apache2 Here is the result of the "free" command : ------------------------------------- total used free shared buffers cached Mem: 2070444 1979116 91328 0 111444 1012000 -/+ buffers/cache: 855672 1214772 Swap: 923696 0 923696 I monitored the used memory (which is given by "-/+ buffers/cache") and sometimes I noticed peaks to 1.6 Gb (which is really high); it wasn't the case before the update, with the same traffic load. Activated modules are : actions.load authn_file.load authz_host.load bw.load dir.conf fastcgi.conf negotiation.load status.load alias.load authz_default.load authz_user.load cgid.conf dir.load fastcgi.load rewrite.load suexec.load auth_basic.load authz_groupfile.load autoindex.load cgid.load env.load mime.load setenvif.load And here are a few details about the Apache 2 version I'm using : ---------------------------------------- Server version: Apache/2.2.3 Server built: Jan 27 2008 18:09:58 Server's Module Magic Number: 20051115:3 Server loaded: APR 1.2.7, APR-Util 1.2.7 Compiled using: APR 1.2.7, APR-Util 1.2.7 Architecture: 32-bit Server MPM: Worker threaded: yes (fixed thread count) forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/worker" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="" -D SUEXEC_BIN="/usr/lib/apache2/suexec" -D DEFAULT_PIDLOG="/var/run/apache2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf" I really hope some of you will be able to help me, I thank you all in advance.
