In addition I see the following when doing a graceful restart of httpd:
[Mon Jun 26 14:17:14 2006] [notice] Graceful restart requested, doing
restart
[Mon Jun 26 14:17:15 2006] [error] (9)Bad file descriptor:
apr_socket_accept: (client socket)
[Mon Jun 26 14:17:59 2006] [notice] Digest: generating secret for digest
authentication ...
[Mon Jun 26 14:17:59 2006] [notice] Digest: done
I find very little on what the "Bad file descriptor: apr_socket_accept"
error means.
I am using Apache/2.2.0 on Linux 2.6.16-1.2133_FC5smp
