If a 12.XX client is talking to a server which does not support the hardware-info messages, it will queue calls to lshw in memory.
if the server the client is talking to is then upgraded, and starts supporting hardware-info, all those lshw calls will happen at once, creating a storm of one lshw process per day it was talking to the old server. This could be just a few processes, or hundreds, depending on how long landscape-client was running and talking to the old server.

A restart will wipe that queue.
