Nothing in the log or event viewer, the service doesn't exit, at some point 
it just stops responding to queries and windows complains about virtual 
memory being too low (naturally).

We got lot's of following errors in the event viewer, which I don't recall 
seeing before, but don't know if it's anyway related:

"too many timeouts resolving '' in [...: 
disabling EDNS."

I'm on vacation so haven't had a chance to investigate this more yet, but 
definitely something's going on there. With 9.4.x we never had any memory 
problems, now after upgrading to 9.5.0 every server runs out of memory in a 
few days. Typically named process took about 40-50M of memory, now when I 
restart the service it's about 30M and grows to over a gig in a few days.
