I have similar but not identical symptoms when using shm.
OS: SunOS bluestem1.cso.uiuc.edu 5.6 Generic_105181-06 sun4u sparc SUNW,Ultra-2
CPU: Ultra 2300 (2 x 300 MHz)
apache-1.3.6
mm-1.0.6
mod_ssl-2.3.3-1.3.6
openssl-0.9.3a
rsaref-2.0
In my case, accesses to the server start failing with "Document contains
no data" or "Connection refused", with error_log messages like these:
[Thu Jun 10 07:37:04 1999] [notice] child pid 28852 exit signal Bus Error (10)
[Thu Jun 10 07:37:10 1999] [notice] child pid 28853 exit signal Bus Error (10)
[Thu Jun 10 07:37:22 1999] [notice] child pid 28854 exit signal Segmentation Fault (11)
In my case, this problem is almost certainly related to shm
session cacheing and more specifically to cache expiry processing.
When I had SSLSessionCacheTimeout set to 7200, these problems
began a little over 2 hours after server startup. When I reduced
the time out to five minutes, the problem started about five
minutes after server startup.
The same production server configured to use dbm cacheing does
not have these problems.
