You uploaded the wrong patch. They do have the same commit message and
fix a similar problem though.

You uploaded: 1c1800755d99e4c5d3cfb5d15ac316383dc97cbd
The correct commit is: e14a9bc5b63d9399dbabad4e63313079e4c6e8bb

I suppose you can leave the current one as well as it obviously fixes
things, and fixing things is always good :)

Thanks

I uploaded a new release into unstable with this patch.
Can you guys have a test?

If it works well, I will start the process to upload it to Stretch.

Apparently this commit fixes the problem. I have a fix running locally,
it would be nice if this could get backported.

Thanks

Here is a new bt, I am not sure it is related, but I am now getting
these all the time after the average 2s of indexing is done in searchd.
