Parallels H-Sphere apache 2.* based web server crashes with segmentation fault (and even core dumped) during start:
# /etc/init.d/httpd start
/etc/init.d/httpd: line 158: 4873 Segmentation fault (core dumped) $HTTPD $DSSL -f $HTTPD_CONF
The reason of the crash is:
#0 0x00d03ee7 in ssleay_rand_status () from /hsphere/shared/apache2/modules/mod_ssl.so
Cannot access memory at address 0x18
The problem is related to openssl bug:
that appears in OpenSSL versions before 0.9.7k and 0.9.8c.
To solve the problem OpenSSL should be updated to the version greater than 0.9.8c.
In case Parallels H-Sphere do not provide own SSL packages, customers should do the update or ask operating system vendor for corresponded support.
