Comment (by cohosh):

 I'm having trouble reproducing the every 7min behaviour, but I do see the
 usual timeouts after 30s of inactivity (#25429). It's possible this has a
 noticeable affect on the browsing experience if the user makes a new
 request right as the client is timing out.

 In any case, this seems to be a client-side issue rather than with the
 proxies. There's two possible quick solutions:
 1. We could set the timeout to a much larger values as suggested in #25429
 2. We could set the snowflake client option `-max 2` or some number higher
 than the default of 1. I'm not entirely sure whether this will help but
 the source code seems to suggest that we will then collect 2 snowflakes
 and can switch to the other one when one snowflake stops working (or times
 out).
