1.) Start Nightly
2.) Open macOS Activity.app

The Opendirectoryd process has a very high CPU usage.

I can not kill the process. I have to restart the Mac!

Could this be related to bug 1383742?

I only see opendirectoryd going crazy after a restart-/shutdown-crash,
not when starting Nightly after a clean shutdown.

It happened to me after a clean install and after the Nightly Update process.

here my STR:

1) open >Developer Toolbar< (shift+F2)
2) run >restart< command 
3) Nightly tries to restart.
4) process crashes?
5) manually start Nightly

opendirectoryd is pinned at 100% CPU.

Thanks. So this is a regression and needs a bisect to find where the regression starts. May be as noted by you in comment 2 related to bug 1383742?

This is still an issue in latest Nightly. Can you please take a look? Nightly consumes a lot of battery at the moment because of this bug :-( Thanks!

The only place I see opendirectoryd being used in our code is sandboxing

Mehmet, could you give the latest Nightly a try and see if the problem is fixed?

This bug is likely to be a duplicate of bug 1338651 which is now fixed. That bug has a huge amount of comments, but the short story is that the way we were building Firefox was sometimes triggering the OS to try to read from some nonexistent paths which results in opendirectoryd getting severely loaded.

Bug 1338651 is a dupe and was also reported due to opendirectoryd and automountd spikes too.

I haven't seen/noticed it since a few days. I think we can close this. Thanks.
