org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend

running 30 parallel db connections all doing inserts, each to its own table. So I have 30 tables, no contention. what does this error mean? Google gives various scenarios.

org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.

Thanks

Hi Allen,

Looks like the only other reference I can find to this is ancient history: https://github.com/cockroachdb/cockroach/issues/3819

So we’re probably doing something new. Does the cluster look otherwise healthy after the error is emitted? Are there any corresponding errors in the CRDB logs?

well, rats. I wiped out my environment (including logs) and am trying to repeat. sorry.
