12.9. SSL Settings
SSL Processing Priority
The maximum amount of CPU resources that SSL processing is allowed to use for opening new
SSL connections. This setting affects all cOS Core subsystems that make use of SSL processing.
If the proportion of CPU time allocated is not sufficient then some SSL connection setups may fail
under a heavy SSL load and the following log message will be seen:
SSL Handshake: Disallow ClientKeyExchange. Closing down SSL connection
The solution to the problem is to increase the maximum CPU resources available from the
default setting of Normal (about 17%) up to either High (about 25%) or Very High (about 50%).
However, a higher CPU allocation may adversely effect the responsiveness of other cOS Core
subsystems.
Lowering the priority is not normally needed unless there is a reason to reduce the CPU time
allocated to SSL connection setup.
Default: Normal (about 17%)
