Dear users,Finally, I think I've found the problem. On freebsd, devel/apr1 chooses apr lock method as flock. Thus, a file is used for synchronization purposes. mod_fcgid creates a temporary file in fcgid_mutex_create() using tmpnam(), which effectively creates a temporary file in /tmp. And in my freebsd setup, I've enabled /tmp cleaning as well, which removes the lock files after a fix amount of time. As apache/apr only opens the file for writing, but actually not writing anything to it, the files {a,c,m}time parameters dont change, so the /tmp cleaning process cannot detect if the files are still in use, it simply removes them.
Either mod_fcgid should use a file located elsewhere, or be configurable, or maybe apr could choose another lock method on freebsd. As on a gnu system, it chooses systemv semaphores, as I've noticed.
Please comment my investigation. Regards, 2013-11-04 18:08 időpontban Richard Kojedzinszky ezt írta:
Dear Users, I am having issues when installing mod_fcgid under freebsd. I have installed www/apache22 from ports, as well as www/mod_fcgid. After some days of running, many of this error message appeared in httpd-error.log: [Sat Nov 02 09:49:28 2013] [emerg] (2)No such file or directory: mod_fcgid: apr_global_mutex_child_init error And after hours passed, the entire httpd process stopped working. Only two httpd processes left running, but they were not accepting connections. I had to restart apache, then it worked again.I am using prefork mpm, and have set MaxRequestsPerChild to a non-zero value.Unfortunately, right now I cannot reproduce the problem, unfortunately it arises randomly. Because I did not find any useful regarding this on the web, I am requesting help here. What could I do to investigate the problem? Thanks in advance, Kojedzinszky Richard
