Hello,

I have upgraded one of my mpd5 based PPPoE access servers from 7.3-RELEASE to
7.4-RELEASE. Just after upgrade, I started getting following errors:

Mar 31 13:48:06 lsm-gw mpd: [B-150] Bundle: Interface ng149 created
Mar 31 13:48:06 lsm-gw mpd: [B-150] can't create ppp node at ".:"->"b150":
Operation not permitted
Mar 31 13:48:06 lsm-gw mpd: [B-150] Bundle netgraph initialization failed

Mar 31 13:48:06 lsm-gw mpd: [zemborzyce-156] LCP: state change Opened --> Stopping

[root@lsm-gw /var/log]# grep -ic "operation not permitted" mpd.log
1756

It seems to occur only on specific bundles and after brief period of time,
session establishment eventually succeeds. Is this related to resource shortage?
