Resolved - Due to network expansion and the need for additional capacity, we will be introducing additional IP addresses from which SIP signalling and/or media may appear to originate. If you have firewalls or ACLs configured to whitelist our IP ranges, we would encourage you to check the updated list available at https://kb.nimvelo.com/article/457-ip-addresses-and-whitelisting to ensure all ranges are included.

Resolved - A single instance of our edge proxies was seeing intermittent spikes and exhaustion of internal shared memory. This was not an exhaustion of available memory, simply of that it was configured to use. When this happened connections would fail and in most cases retry again. This also affected websockets (and thus Communicator) where calls were balanced to the affected Kamailio whilst it was having issues.

Following yesterday’s loss of the Leeds site, DNS was repointed to London to cater for client devices which do not support SRV properly, before being restored. We believe a large number of those devices also cached stale DNS causing an imbalance of connection attempts and the spikes in memory usage.
With this limit increased, whilst we still see an imbalance of client requests, they are more than adequately handled.

We apologise to those intermittently affected by this elusive issue.
