Bug ID: 194919
Summary: kernel: pid 2509 (named), uid 53, was killed: out of
swap space
Product: Base System
Version: 10.0-STABLE
Hardware: amd64
OS: Any
Status: Needs Triage
Severity: Affects Some People
Priority: Normal
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: vistah...@qq.com
In one of our slave DNS servers BIND, version bind910-9.10.0P2_5, constantly
get killed with the following message in /var/log/messages:
Nov 9 05:11:14 zsusun2 kernel: pid 2509 (named), uid 53, was killed: out of
swap space
This service runs on a FreeBSD 10.0 VM in XCP 1.6, it has 922MB of system
memory.
At this moment swapinfo return this:
Device 1K-blocks Used Avail Capacity
/dev/ada0p3 944128 9060 935068 1%
I don't think it's a swap problem, it appears to be memory leakage, but I'm
unsure.
This is one of two slave DNS servers, they only store the zones from the
authoritative server and act as a recursive server for the internal users to
the outside world. The number of clients is something between 700-1500
simultaneous users. Since we have a /21 internal space and a /23 public IPv4
space and there's no queries from the outside world, the port 53 is even
blocked on the firewall to those machines.
