Обсуждение: TCP_KEEPIDLE Question
Hello,
I am running postgresql 9.3 (installed via the apt.postgresql.org repository) on Ubuntu 12.10. I just upgraded from 9.2 on a dev machine, and when looking through the logs, I noticed that there were a lot of entries stating "LOG: setsockopt(TCP_KEEPIDLE) failed: Invalid argument".
I was wondering if anybody had seen this before, and what this was an indication of.
Thanks,
Grant

Hm, that's the kernel call corresponding to our GUC parameter tcp_keepalives_idle --- have you set a nondefault value for that? For implementation reasons, a bad setting for that is likely to result in this log message and no other indication. Another possibility is that your kernel doesn't allow this parameter to be set ... but that seems pretty unlikely for a reasonably-vanilla Linux kernel. regards, tom lane
