I'll be asking 'those in charge' to reset some timeout/keep-alive setting /somewhere/. I need help in hopefully naming the correct setting. The server is running version 14
Am I dealing with a client issue, a server issue or a mis-match in host/postgres configuration values? If I cannot have psql wait forever, I would at least like it to die/reconnect quickly. What are my options?
If I leave my psql session for long enough, then the first interaction (with some exceptions) will be unresponsive for /some time/. The typical, eventual response is a successful re-connection though last one was fatal:
psql:/uufs/chpc.utah.edu/common/HIPAA/u0138544/gits/gitlab/sgs5/jooq/src/main/resources/db/scripts/functions/showSegmentCalls.sql:22: SSL SYSCALL error: Connection timed out psql:/uufs/chpc.utah.edu/common/HIPAA/u0138544/gits/gitlab/sgs5/jooq/src/main/resources/db/scripts/functions/showSegmentCalls.sql:23: no connection to the server psql:/uufs/chpc.utah.edu/common/HIPAA/u0138544/gits/gitlab/sgs5/jooq/src/main/resources/db/scripts/functions/showSegmentCalls.sql:23: fatal: connection to server was lost
More typically I get this
