It's a typical out-of-memory situation, where some part of the kernel
consumes more memory than is available or can be freed.
So, different kernel subsystems start to fail.

If it starts to occur after your changes, I guess that the out-of-memory
happens because you insert packets in the queue without any limits on the
queue length or source throttling.
