vcl woes

[epixoip]

It means your broker ran out of memory. The only person I know who has had this problem ended up having a misconfigured network, where he tried to multi-home each node but he put the second NICs on a separate subnet that was routable back to the primary subnet, so the broker was having to handle multiple replies from each host for each kernel execution. So make sure your VCL traffic is on an isolated network.
