I saw it in another bug today, too.

This error is happening only on webkit-cq-02 machine. Logs on webkit-cq-01 and webkit-cq-03 doesn't have this error. I just manually run "git prune" on webkit-cq-02. Let's see if that helps.
Comment 4 Alexey Proskuryakov 2018-03-07 09:03:25 PST
This night, it happened on webkit-cq-01 in bug 183400.
Comment 6 Aakash Jain 2018-03-07 15:39:44 PST
Observation: The issue didn't happened on webkit-cq-02 after I run "git prune" yesterday night. It started happening on webkit-cq-01.
Comment 7 Aakash Jain 2018-03-07 15:40:10 PST
Did following to fix/improve this:

1) Run "git prune" on all the webkit-cq-* machines. 

2) Configured following variables to have better git gc:

git config --global gc.reflogExpire 30    (defaults to 90 days)
git config --global gc.reflogExpireUnreachable 10  (defaults to 30 days)

Reference: https://git-scm.com/docs/git-gc#_configuration

3) Running "git gc --aggressive" currently.
Comment 8 Aakash Jain 2018-05-25 16:24:23 PDT
Closing it as we haven't seen this issue again after doing configuration changes.
