Hi Zach,
One of our perf. team ran into this while doing some runs.
I didn't see anything obvious - it looks like we converted
async IO to synchronous one. I didn't spend much time digging
around.
It looks pretty bad, a *shouldn't happen* kind of case. I'm sure it
just means I missed some case :/.
Is this a known issue ? Any ideas ?
I haven't seen it before, no. Do they have a reliable recipe to
reproduce it?
In any case, I'll dig in early next week when I'm back from OLS. I'm
pretty confident that we'll be able to find the case. Please let me
know if it's urgent and I should try and find time before then.
Thanks for reporting it.
I asked our perf. team to reproduce and print out refcount, if this
happens again.
We can look at it when we get back.
Thanks,
Badari
