The sysctl option
net.core.somaxconn defaults to 128 (on our systems) but can be raised.
What exactly is this limit measuring and capping?
How do I find out how close I am to the limit?
Context: I had a problem recently that appeared to be corrected by raising this limit. The problem was intermittent, so I don't trust that it is really fixed. I would like to find out if the current number of [whatever this setting caps] is greater than the previous maximum limit of 128.
