Stuck for very long time on bulk request

[Boaz Citrin <bc...@gmail.com>]

Hello,

We recently encounter a situation where after using database for a while it
starts hanging on bulk requests.
Even those with just a single doc, regardless of the result, being ok or
conflict, can sometimes take 2 minutes.

This is with version 1.6.1 on Windows.

No errors on log.
Enabled debug and couldn't see anything other than requests, except the
following:

Any idea?

Thanks.
