Error: unknown event(831) / event(2125) in fsevents.

My lsyncd keeps on crashing after initial sync with this error message:
Error: unknown event(831) in fsevents

Strange is that the initial scan works just fine and the moment when it is crashing varies also, so I do not know what is triggering it. Any ideas?

EDIT: It crashed now with the error code:
Error: unknown event(2125) in fsevents.

The system I compiled lsyncd on is Lion 10.7.5

Quite strangly the last week not one crash. Anyone?

I guess its the FS_EXCHANGE event that Apple seems to have introduced somewhen, that is two files are exchanged. I don't know yet how to handle this further down in the Lsyncd chain.

It should be reproducable with opening a watched file with some editors.

Thanks axkibe, I will give it try to reproduce the error and see if it crashes again. Anything else I can provide you with?

This is still happening to me right now.

This just happened to me on Yosemite.

Yes, the whole FsEvents part of Lsyncd should be rewritten. However, unless we find someone willing to do that I'm thinking of dropping fsevents from Lsyncd all together, the current implementation is buggy and uses non-documented interfaces.

Hey There! This issue is coming up again, and I am not sure how to debug it. I have been trying to use fs_usage to monitor the event but to no avail. This is preventing me from using lsyncd, it crashes right after the first sync on my Macbook, every time.
