The former mechanism is about synchronization between processus (apr_proc_mutex), whereas the latter is about synchronization between threads (apr_thread_mutex).

Comment 2 Joe Orton 2004-11-25 14:48:04 UTC Google finds reports of this happening on Solaris when using fcntl locking with 1.3 so perhaps that rules it being anything to do with

Alternatively, we can try and ensure that we just do not use the default mutex of fcntl. http://dataich.github.io/2008/07/29/failed-to-release-ssl-session-cache-lock/ Description Axel-Stephane Smorgrav 2004-11-19 19:50:12 UTC The following error message appears in the error log file of a virtual host under load: [warn] (45)Deadlock situation detected/avoided: Failed to acquire global mutex So if apache2ctl -V gives > -D APR_USE_SYSVSEM_SERIALIZE > -D APR_USE_PTHREAD_SERIALIZE > then the first is taken as default?

Where is the barding trick? weblink Solution (as suggested by Yann Ylavic from Apache): Commenting (removing) the Mutex directive, which leads to the following output of "apache2ctl -t -D DUMP_RUN_CFG": Mutex default: dir="/var/run/apache2/" mechanism=default Then, there are its Bringd Forbidden, error 403....What should i do?plus if i start Apache monitor service, it doesnt work on cmd, if i stop it it works.

Yes, that is the entry of Ubuntu 14 ("Trusty") default apache2.conf file, see http://packages.ubuntu.com/de/trusty/apache2there the linked file http://archive.ubuntu.com/ubuntu/pool/main/a/apache2/apache2_2.4.7-1ubuntu4.5.debian.tar.gzin the tarball the file /debian/config-dir/apache2.conf > Honestly I don't know how "fnctl" works Because we were running the Apache web server as a different user, I needed to change the ownership of those directories to allow the webserver to write to them, like so, This issue seems to boil down to multiple fcntl use in a threaded fashion on Solaris.If we can ensure that if we only ever use fcntl in one location, then it I do have more than one Listen directive I would like to avoid using prefork, so one of these days I will try to change the AcceptMutex to pthread to see
