Unable to establish communication with the peer (PMType) process manager. Comms error (Errno).

Draft comments: Suggestion for Dev: “process manager” is the original SWIPE terminology. I think it should be changed to “process sentinel” to reflect the later usage that was adopted, and to match the user docs.

Description 

The PMType (either Worker or Watcher) process sentinel cannot create a TCP/IP socket connection to its peer process, because of a socket Errno. This means that the PMType process sentinel will be unable to restart its peer process, if the latter fails.

The watcher and worker process sentinels ensure that they remain running at all times by connecting to each other over TCP/IP sockets. Each sentinel process on a machine creates a connection to the other process to ensure that its peer is running and to detect any failures.

Severity 

2 (Severe)

Action 

To rectify this problem:

1. See the socket documentation for your particular operating system for more information about the socket Errno, what might have caused it, and how to resolve it:
2. In the UNIX /etc/services (or Windows %systemroot%\system32\drivers\etc\services) file, make sure that the TCP/IP port numbers assigned to the nodename_watcher and nodename_worker processes are unique (system-wide).
3. Ensure that all network adapters are correctly configured.
