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 .

When this error started to happen? After kernel upgrade? After pppd
upgrade? Or after system upgrade? Or when more users started to
connecting?

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.

These are userspace error messages, not kernel messages.

What kernel version are you using?

Yes, we need to know, what kernel version are you using.

thanks,

greg k-h

And also another question, what version of pppd daemon are you using?

Also, are you able to dump state of ppp channels and ppp units? It is
needed to know to which tty device, file descriptor (or socket
extension) is (or should be) particular ppp channel bounded.
