Hi All,
We're running two nodes using with replication enabled.
pgpool routinely (every day) performs a failover with the following statements appearing the in log:
2017-02-15 13:16:01: pid 16190: WARNING: write on backend 1 failed with error :"Success"
2017-02-15 13:16:01: pid 16190: DETAIL: while trying to write data from offset: 0 wlen: 5
The source code (pool_stream.c:pool_flush_it()) seems to consider a write of 0 bytes an error. Also the "Success" in the log statement indicates that errno was not set.
There never appears to be any actual problem with the node.
Should pgpool trigger a failover in this situation?
Thanks,
Dave
