--------------------------------------
Summary: Malfunction agent may block future SSL connection to the
server
Key: CLOUDSTACK-5723
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5723
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0, 4.3.0
Reporter: Sheng Yang
Assignee: Sheng Yang
Priority: Critical
Fix For: 4.2.1, 4.3.0
If one agent failed to process the SSL handshake process, it would block the
future incoming connections to mgmt server.
Then all the future connection to the mgmt server would be hold infinitely
until the malfunction agent exit.
The reason is we use blocking mode in communication when try to do SSL
handshake process, though we have mechanism to protect mgmt from malfunction
agent who try to exchange handshake info too many times, we don't have
mechanism on stop one agent didn't response the handshake.
