Subject: Urgent  Bug report: PPPoE ioctl(PPPIOCCONNECT): Transport endpoint is
 not connected

Hi Net dev team


Please check this error :
Last time I write for this problem : https://www.spinics.net/lists/netdev/msg707513.html

But not find any solution.

Config of server is : Bonding port channel (LACP)  > Accel PPP server > Huawei switch.

Server is work fine users is down/up 500+ users .
But in one moment server make spike and affect other vlans in same server .
And in accel I see many row with this error.

Is there options to find and fix this bug.

With accel team I discus this problem  and they claim it is kernel bug and need to find solution with Kernel dev team.
