If the dst socket is closed, sbuf_send_pending will fail but not mark the operation as failed. It will then retry repeatedly, consuming a lot of CPU until pgbouncer is restarted.

How do you get into that situation? Is that something we can cover with a test case? |

I'm not sure how it happens. It doesn't happen often. But when it happens it's really bad. pgbouncer starts using 100% of it's CPU core and starts flooding the logs with errors. The only way to stop it is by restarting it. Please merge this simple workaround for this issue. |

@petere we are looking forward to this fix |

Is this likely to make it into the next release? we started hitting this error in version 1.12 have then updated to 1.16 & 1.17 where we are still experiencing it... its very intermittent. |
