This is a build that *was* working. I've been using it--I see (see
below) since December.

This returns:
Server version: Apache/2.2.25 (Unix)
Server built: Dec 2 2013 08:47:03
Server's Module Magic Number: 20051115:33
Server loaded: APR 1.4.8, APR-Util 1.5.2
Compiled using: APR 1.4.8, APR-Util 1.5.2
Architecture: 64-bit
Server MPM: Prefork
threaded: no
forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS

So I can ditch the worker section?

Thanks for the strace trick:
= 0
munmap(0x7fbfdc208000, 4096) = 0
write(43, "[Thu Jan 16 23:57:11 2014] [error] Unable to configure
verify locations for client authentication\n", 98) = 98
exit_group(1) = ?
I gather this is an SSL problem. Here is the section of that
configuration that is changed. It is a new certificate (that includes
the new subdomain):
Include /etc/httpd/conf/sites-available/all-ssl-common
SSLCertificateFile
/big/www/ssl/parts-unknown.org/munich/parts-unknown.org.crt
SSLCertificateKeyFile
/big/www/ssl/parts-unknown.org/munich/parts-unknown.org.key
SSLCertificateChainFile
/big/www/ssl/parts-unknown.org/munich/sub.class2.server.ca.pem
SSLCACertificateFile /big/www/ssl/parts-unknown.org/munich/ca.pem
These files all exist. all-ssl-common is unchanged. It contains:
SSLEngine on
SSLProtocol -ALL +SSLv3 +TLSv1 +TLSv1.2
SSLCipherSuite
ECDHE-RSA-AES256-SHA384:AES256-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM;
SSLHonorCipherOrder on
SSLCompression Off
#SSLCipherSuite RC4-SHA:HIGH:!ADH
SSLInsecureRenegotiation off
SSLOptions StdEnvVars
BrowserMatch "MSIE [2-6]" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
Thanks!
