Valentin Kulichenko commented on IGNITE-2951:
---------------------------------------------
The following is done:
* Removed serialization buffer from discovery message worker. This fixed OOM
issues.
* Fixed race in continuous processor. {{clientInfos}} map was not copied before
adding to the message. This could cause concurrent serialization and
modification.
Changes are committed to master:
