Hi,
 I could not figure how to reproduce that. My main process remained
unchanged after reloads using the sample config and certificate auth.
Could you send me some steps to be able to reproduce the issue?

If there is some issue it should not be apparent as all the
certificate handling is done on the worker process (where leaks don't
really matter) or the sec-mod process. Fortunately sec-mod seems to
remain unchanged after your reload.

btw. did you have any issues with the "enable-auth certificate"
option? Its purpose was to eliminate the need for two servers.
