Summary 0000162: To start watchdog pgpool nodes simultaneously is not safe
Revision 2015-12-25 13:13 by t-ishii
Description To start watchdog pgpool nodes simultaneously is not safe.
There is the case that the following happens.

- "FATAL: failed to initialize watchdog, delegate_IP "x.x.x.x" already exists"
- Master nodes more than two are born
- The recognitions of the invalid node are not consistent.

There are not robust initial coordination logic.
So I think that we describe clearly "must start it one by one" to the manual.
