Nick Couchman commented on GUACAMOLE-919:
-----------------------------------------
[~DouglasHeriot]: For you, yes, this is a show-stopper. The reason it has been
classified as minor is that we only have two people reporting it at this time,
and we don't really even know exactly what's causing it. We've identified a
couple of possibilities for what might fix it, but, as far as Guacamole is
concerned, it isn't a bug, it's an enhancement to overcome what we suspect is
happening in a couple of specific situations related to timeout/latency between
client and DB. It isn't being widely reported throughout the community on
either 1.0.0 or 1.1.0, it seems to be pretty limited, so that's my rationale
for having classified it as minor.
As far as it being a regression - I'm skeptical of that. It is very
interesting to me that it works for you in 1.0.0 and not in 1.1.0, but if you
look at the original reported issue, it is against version 1.0.0, not
1.1.0-RC1. I don't know exactly what to make of that, but the fact that it is
being reported by you and the original reporter in two different versions makes
me think that it isn't a regression between those two versions, it's something
else. Is your 1.1.0-RC1 deployment running on exactly the same systems as
1.0.0, and using exactly the same Postgres server, so that the only difference
between the two is the Guacamole version? And you're saying that, if you go
back to 1.0.0 right now (in the environment where 1.1.0-RC1 does ont work),
that everything works as expected?

> 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
