[issue41642] RHEL and fedora buildbots fail due to disk space error

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

The buildbot server migrated to a new machine and is now behind a load balancer. tcp/80 (buildbot web page, HTTP) and tcp/9020 (used by buildbot workers) are both behind the load balancer.

Maybe the load balancer closes TCP connections which are idle for 60 seconds?

Buildbot workers have a TCP keepalive option of 1 hour (3600 seconds) by default:
https://docs.buildbot.net/latest/manual/configuration/workers.html#master-worker-tcp-keepalive

Pablo told me that his worker uses a keepalive of 2 minutes (120 seconds).
