500 errors and stale comments on crbug

Project Member Reported by pdr@chromium.org, May 9 2018

Issue description

I think this may be related to the database change made last night. I'm seeing frequent 500 errors. I'm also seeing stale pages where I leave a comment but the comment does not show up until I refresh the page a second time.

emaxx recently commented on the chromium-dev thread. I think they may be reporting the same issue.

We have a fix for this already landed.  It should be deployed today.

This is caused by DB replication lag.  It has been a problem for a while, sometimes worse than other times.  The schema changes made last night should not have affected it (other than lag that occurred during the maintenance window itself).
Correction:  This is not the normal problem of replication lag because it happens repeatedly.  I am looking for the cause.

The fix for the lag should in fact resolve this problem.  But, I also want to find the cause.

It was not the normal DB replication lag, it was a completely stuck DB replica.  It affected both comments and search results.  Please see issue 841457 for further details about the cause.
