OS X

happened twice in a row after getting a new build

[jesuscript]

[update] happens every time I try to shut it down

[rphmeier]

(please reopen if the problem persists)

[jesuscript]

still happening (built master a few hours ago)

[rphmeier]

this will be exacerbated by doing blocking tasks (e.g. snapshotting) in the io threads.

[jacogr]

Same on my side. Let me know if I can supply any additional info - basically I get zombies around every 2nd shutdown.

[chevdor]

Having the issue as well but only during Syncing. Once parity is synced (you see Imported.... messages in the logs), it no longer happens.

Does this still occur?
