        There are many flushes in the log. I took a peek on the one of them only. In that particular case deletion of one of vbuckets took more than 20 seconds. This is known issue. In some cases vbucket deletion can take a lot of time. Sooner or later flush will finish but our UI timeout for this is only 30 seconds. One suggestion is to disable file system barriers or its windows equivalent (see attached image). It's known to speed up flush significantly.
