Signed-off-by: Rohit Yadav <rohit.ya...@shapeblue.com> > CloudStack Server degrades when a lot of connections on port 8250 > ----------------------------------------------------------------- > > Key: CLOUDSTACK-9348 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9348 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Reporter: Rohit Yadav > Assignee: Rohit Yadav > Fix For: 4.9.0 > > > 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: > https://github.com/apache/cloudstack/blob/master/utils/src/main/java/com/cloud/utils/nio/NioConnection.java#L125 > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
