bind: named hangs systems because it exhausts memory

Package Name

bind

Maintainer

@nmeyerhans

OpenWrt Version

SNAPSHOT

OpenWrt Target/Subtarget

x86/64

Steps to Reproduce

1. Install both isc-dhcp-serve and bind-server
2. Configure dynamicdns so that updates are sent to named
3. Let it run for a few days

Actual Behaviour

It will eventually exhaust system memory and crash.

Possible Fix
To the init file add:

proud_set_param limits "data=nnnnn"

so that if it is leaking memory, it eventually crashes and gets restarted rather than compromising the entire system. (Or possibly "as=nnnnn".)

Question is, what's a reasonable amount of memory for it to run in? On my system with ~200 hosts, it's taking:

root@OpenWrt:~# ps -p $(pidof named) -lll
F S   UID   PID  PPID  C PRI  NI ADDR SZ WCHAN  TTY          TIME CMD
4 S    57 18981     1  3  80   0 - 12458 do_epo ?        00:37:20 named
