Mechanix commented on GUACAMOLE-919:
------------------------------------
[~DouglasHeriot]thank you very much for this thorough investigation.
{quote}I'm guessing that AWS RDS is just dropping long-lived idle connections
without closing them? Or it could be some other network configuration issue we
need to solve?

Our PostgresDB is running outside k8s on bare metal though.
I'm looking forward to see this issue fix. If you need a testing hand, let me
know.

> Hi,
> we use guacamole with postgresql and openid extension. Guacamole and guacd is
> deployed inside a k8s cluster.
> For some reason, the authentication doesn't succeed sporadically; there is
> only a blank page and this error message in the guacamole log:
> *[pool-1-thread-1] WARN o.a.i.d.pooled.PooledDataSource - Execution of ping
> query 'SELECT 1' failed: An I/O error occurred while sending to the backend.*
> I suspect there is a weird timeout happening between guacamole and postgresql
> but could figure out why.
> Any hints are much appreciated. Thanks
