Hi,

I am managing several web servers with a very similar configuration. On
one instance I get a segmentation fault if I specify the
SSLCertificateChainFile option (I am using 2.0.58).

If I remove the directive the problem disappears.

- - the certificate file is OK (it is the very same file I use for other
  instances which are working w/o problems)

- - executing httpd with strace I get the following

[...]
fcntl64(10, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0
open("/etc/apache/vhosts/129.132.46.76/conf/ssl.crt/sureserverEDU.pem",
O_RDONLY|O_LARGEFILE) = 11
- --- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

- - the log files (LogLevel debug) do not show anything useful

Do you have idea what I could try or where else I could look for info?

Many thanks in advance

Matteo
