ASF GitHub Bot commented on CLOUDSTACK-9348: -------------------------------------------- Github user swill commented on the pull request: https://github.com/apache/cloudstack/pull/1493#issuecomment-219555128 @rhtyd I reverted this in master to hopefully unblock my CI environments from failing as I am basically at my freeze date. Would you mind putting the above commits together in a single PR and reopen it? We know what we are looking for when we test it on its own again. > 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 (v6.3.4#6332)
