We periodically receive this error:

which we resolve by running gerrit GC. We believe the issue is that our repo gets too large to fetch over HTTP. We're getting to the stage now where we need to run this action multiple times a week, so soon the workaround won't be viable. Can you modify the checkout processes to go via SSH instead of HTTP?
