Hi all.
I compiled nginx against pcre 8.21 and jit enabled. With this scenario in a few days the nginx processes are using more than 100MiB of RAM each. The same scenario with nginx 1.1.12 compiled against the system pcre library and jit disable (not available) the nginx processes are not consuming more than 13MiB each (as expected).
CentOS 6.x nginx 1.1.12 ./configure --with-pcre=../pcre-8.21/ --with-pcre-jit --with-http_stub_status_module --with-http_ssl_module --without-select_module --without-http_ssi_module --without-http_userid_module --without-poll_module --without-http_ssi_module --without-http_autoindex_module --without-http_geo_module --without-http_map_module --without-http_split_clients_module --without-http_referer_module --without-http_uwsgi_module --without-http_scgi_module --without-http_memcached_module --without-http_limit_conn_module --without-http_limit_req_module --without-http_browser_module --without-http_upstream_ip_hash_module --without-http-cache --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module
I'm not sure if the memory leak is related to nginx, pcre, configuration or a mix. Please let me know if more information is needed, configuration files, etc.
Yes, please, provide your nginx config.
Which version is your system PCRE library? Does it leak when the "pcre_jit" directive is switched off?
Just for update. I sent my configuration privately to Valentin, and he found a memory leak, he wrote a patch that works as expected, so I think that will be fixed in 1.1.14.
Thanks so much to Valentin.
Kind regards.
