What causes the error "Security: 149 - digest check failed, SSL Connect" when loadtesting an Apache Web Server?
By default SSLSessionCache is not set which disables the global/inter-process Session Cache.
Setting SSLSessionCache should resolve the "Security: 149 - digest check failed, SSL Connect" error.
from mod_ssl help - http://www.modssl.org/docs/2.8/ssl_reference.html:
"This makes use of a DBM hashfile on the local disk to synchronize the local OpenSSL memory caches of the server processes. The slight increase in I/O on the server results in a visible request speedup for your clients, so this type of storage is generally recommended."
It is recommended you discuss this issue with your server administrator before proceeding.
