[GLLUG] radvd leaking memory

[Tim Woodall]

Hi,

Last night radvd got killed by the oom killer
Feb  4 02:32:11 firewall17 vmunix: [1762825.239631] [  pid  ]   uid  tgid total_vm      rss pgtables_bytes swapents oom_score_adj name
Feb  4 02:32:11 firewall17 vmunix: [1762825.239671] [   3882]   105  3882    68490    19387   581632    48648             0 radvd

When I look on another host I see that it's rather larger than I would
have expected:
3247 radvd     20   0  177228  41016    556 S   0.0  24.0  16:07.26 radvd

After a bounce it looks better:
  1030 radvd     20   0    2444   1616   1476 S   0.0   0.9   0:00.01 radvd


I cannot find anything about radvd having memory leaks. Does anyone know
if this large memory footprint is expected (I'm running it on a VM with
not much memory and I can increase that if necessary)?

I can obviously restart it to avoid this issue. I wonder if it could be
related to VPN interfaces that are constantly being created and removed.

Tim.
