thanks for the reply... this is what happened when I tried your first suggestion:
bash-2.05# /usr/bin/openssl s_server -WWW -cert /usr/local/apache/conf/ssl.crt/www.secure.domainnamehere.co.uk.crt
Using default temp DH parameters
unable to get private key from '/usr/local/apache/conf/ssl.crt/www.secure.domainnamehere.co.uk.crt'
3886:error:0906D06C:PEM routines:PEM_read_bio:no start line
em_lib.c:662:Expecting: DH PARAMETERS
3886:error:0906D06C:PEM routines:PEM_read_bio:no start line
em_lib.c:662:Expecting: ANY PRIVATE KEY
3886:error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:missing asn1 eos:ssl_rsa.c:707:
I have to admit, these messages are well beyond my comprehension.
I'm quite sure that I did provide a key when compilng mod_ssl, though, using the --with-key directive.
As for the coredumps, I can't see any being genereated.
..still hunting
