named (bind9) unexpectedly terminates

When I noticed that my DNS resolution stopped (which didn't take long), I found that the named process was terminating unexpectedly. The bind and bind-tools packages were recently updated to 9.16.1-2. Nothing in my configuration had changed, but the crash started happening. There was no good forensic information to go by, so to I rebuilt bind/bind-tools with the latest 9.17.1 version (the current version is already flagged as out of date).... exact same issue, but I was able to get more information from the logs:

named[100429]: netmgr.c:995: REQUIRE(worker->recvbuf_inuse) failed, back trace

named[100429]: exiting (due to assertion failure)

Searching around didn't reveal any insight other than there were historic problems on other distros with incorrect shared library versions being silently used. A little more digging and I found that the libuv package just upgraded from 1.35.0 to 1.36.0. I tried backing off to 1.35.0. The crash stopped and everything worked normally. To be sure, I also reverted back to bind 9.16.1-2 and had no issue. So without further investigation, it appears that libuv 1.36.0 is the problem. Just posting this for informational purposes in case anyone is facing the same.

Thanks for the report. I'm in the same issue here and I will downgrade libuv.

Re: named (bind9) unexpectedly terminates

I had the same issue on a 32-bit machine. The upgrade to libuv 1.37 solved it for me.
