The new rpc scheduler can have lots of > different queues. Those queues have different capacity limits. Currently the > dispatch method can block trying to add the the blocking queue in any of the > schedulers. > This causes readers to block, tcp acks are delayed, and everything slows down. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
