[~mjumper] we just deployed version 1.1.0 in our k8s cluster and the issue
described persists. As you mentioned, the DB handling was not touched between
1.0.0 and 1.1.0, this is no surprise.

> 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
