2018-02-16T10:01:16.053-0500 Observed that CPU load was very low, server was almost idling. No recent error messages in Confluence's logs (atlassian-confluence.log).
Netstat showed 2055 sockets to port 8090 with 1979 sockets being in CLOSE_WAIT state. 1059 were to 127.0.0.1 and 997 were to ::1, suggesting different methods of opening the connection locally. Under normal operation, usually 100 sockets are open, most in TIME_WAIT state.
CLOSE_WAIT could mean an application error. The attached PDF from Red Hat's Knowledge Base describes the problem in detail.
Restarting Confluence fixes the issue temporarily. Since we don't have a support contract for Confluence, I'm engaging the community to try and identify next steps.
