Subject [jira] [Commented] (CLOUDSTACK-9348) CloudStack Server degrades when a lot of connections on port 8250
Date Mon, 16 May 2016 21:32:12 GMT


ASF subversion and git services commented on CLOUDSTACK-9348:

Commit ed8d47eef2210847a93934d78eb32fc5cfb731fe in cloudstack's branch refs/heads/master from
[;h=ed8d47e ]

Revert "CLOUDSTACK-9348: Make NioConnectio loop less aggressive"

This reverts commit 540d9572fd491db3ce182d26636fc74ada4e171c.

This was reverted because it seemed to be related to an issue
when doing a DeployDC, causing an `addHost` error.

> An intermittent issue was found with a large CloudStack deployment, where servers could
not keep agents connected on port 8250.
> All connections are handled by accept() in NioConnection:
> A new connection is handled by accept() which does blocking SSL handshake. A good fix
would be to make this non-blocking and handle expensive tasks in separate threads/pool. This
way the main IO loop won't be blocked and can continue to serve other agents/clients.
