-------------------------------------------------
{quote}Some errors are generic
{quote}
I want to be sure that there is no case when they might be actually useful.
{quote}What I couldn't figure out was why was it only 2 tests that hit DSE and
the rest were complaining about v5?
{quote}
Can you try to verify this one, please?
{quote}should I remove that restriction in the patch and leave it flaky for 3.x?
{quote}
I personally think that opening a new separate ticket and not silencing those
is the right thing to do.
Unfortunately, I will be off until Thursday, so I don't mind if someone takes
over the review of this one in the meantime and a patch gets merged when
everything is confirmed and ready. I don't want to block it. But I do have
concerns and we need to be very, very careful with all errors we silence,
especially when it is done broadly. I am -1 on silencing 17466, +0 on the rest
as it needs confirmations. Not blocking, but want to be verified very carefully.

> We log unknown exceptions at the networking level, which includes case where
