1.1.1 removed the limit on the number of parallel sockets, and each open socket has a memory cost, so it's not too surprising that OOMs are more common. We can look into the per-socket memory costs and try to figure out if they can be reduced. For example, each socket currently allocates a 5 KB buffer, but that value has not been tuned at all.
