    Description

      Analysis of a heap dump of running OpenDaylight with 10K concurrent NETCONF sessions over SSH transport shows that around 16% of the heap is used by Bouncy Castle's KeyPairGeneratorSpi$EC and related objects – accounting for ~26% of OpenDaylight's per-session memory overhead.

      These objects are retained by org.apache.sshd.common.kex.ECDH's myKpairGen field, which is never used once a keypair is generated.
