SSL memory consumption grows when virtuals with sni-default-enabled clientssl profiles are modified.
The amount of leakage will depending on the number of virtuals with sni-default-enabled clientssl profiles and frequency of configuration manipulations. For large configurations, the leakage can be very noticeable over time.
clientssl profile with sni-default enabled combined with configuration manipulations of virtuals with such profiles.
No workaround short of not using sni-default.
SSL now handles sni-default-enabled clientssl profiles without leaking the X509 objects.
