httpd/APR on FreeBSD uses a file-based mutex ("flock") by default.  It
looks like the mutex files are placed in a location where the httpd child
processes don't have permission.

You should be able to use 2.4's Mutex directive ( to resolve the

Perhaps the necessary magic is

Mutex file:/some/path/ default

where /some/path is writable by httpd parent and child.  I don't *think*
this is some jail-specific issue, other than that child-writable paths in
the jail may be different/more limited due to the way it is set up.
