Hi Folks,

We have HA with Master/Slave database along with pgpool..where application
were connecting via pgpool with VIP..

Suddenly VIP was unable to telnet and application went in waiting state..We
have received frequently below error in pgpool.log file.

2021-07-17 08:12:12: pid 1618597: WARNING: write on backend 1 failed with
error :"Success"
2021-07-17 08:12:12: pid 1618597: DETAIL: while trying to write data from

Could someone help here why VIP went down any causes..

Thanks
