Memory leak in p2p #3306
Description
We have been observing memory usage increase over time (~1MB/min) on our sentries until they were OOM killed.
A heap profile shows that the p2p module seems to be leaking Peers with the recvBuffers of multiplex channels making up the largest amount of memory.
The following heap profile was taken from a normal node on the game_of_stakes_6 network based on v0.30.0-rc0.
