CUCM 8.6 running on VM getting alert KERNEL: assertion (!sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (152)

Hi,

First time to post question here.

We have a CUCM 8.6 running in datacenter in Denver.  We have users located in 3 different sites, 1 in Watkins, 1 in Goldhill and the other one is in Canada.

Lately (past week) our users in Canada are experiencing difficulty in connecting to their VM, placing and receiving calls.  We checked the network and it looks clean.

No packet loss between Canada and the nexus.  The packet loss we are seeing are between the 10G link from Nexus to the VM.

We can see that the NIC running in VM is set to flexible.  We are also seeing this alert when we tried to login to VM...."KERNEL: assertion (!sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (152).

We are thinking this could be the cause of the problem.  Any input would be greatly appreciated, thanks.

 

Regards,

Dante

Hi Dante,This error is more

Hi Dante,

This error is more of a cosmetic one as per the following bug

https://tools.cisco.com/bugsearch/bug/CSCts35326/?reffering_site=dumpcr

You should open a TAC case for issues with voicemail and calls. If you can provide some specific details about the exact issue like what type of calls are failing, frequency of failure, error message or announcement, IP phone models and firmware involved, call flow etc then someone might be able to respond on supportforums.
