Hi everybody I've the next architecture with pgpool (streaming replication mode): 4 nodes 1 Master Node 2 Standbys Node 1 pgpool Node I've disabled the load balancing, because some clients report me problems with the load balancer, they told me the load balancer some times send querys to standby nodes, which has not yet recovered data and the querys fail, but this topic is for another thread. When I try run a stress test with hammerdb I see next errors in the pgpool Node 2015-11-27 16:48:21: pid 20190: FATAL: unable to read data from DB node 0 2015-11-27 16:48:21: pid 20190: DETAIL: EOF encountered with backend 2015-11-27 16:48:21: pid 19182: LOG: child process with pid: 20190 exits with status 256 2015-11-27 16:48:21: pid 19182: LOG: fork a new child process with pid: 20298 2015-11-27 16:48:21: pid 20163: FATAL: unable to read data from DB node 0 2015-11-27 16:48:21: pid 20163: DETAIL: EOF encountered with backend 2015-11-27 16:48:21: pid 19182: LOG: child process with pid: 20163 exits with status 256 2015-11-27 16:48:21: pid 19182: LOG: fork a new child process with pid: 20299 In all Child, therefore the hammerdb stop the test because all connections it lots.
I've never run pgPool myself, but maybe this means the connection was broken for some reason. Are there related errors in the Postgres server log for that node?
