SOMAXCONN - bump up or sysctl?
hey all,
We have a request to bump up SOMAXCONN. Are there are repurcussions to doing so? Would it be better to make it a sysctl?

There is a very serious repurcussion to allowing this be increased in any form, people won't fix their code if you just give them this bandaid.
The new connection backlog controlled by an upper limit of SOMAXCONN is a "buffer" between the kernel and userspace.
It is _NOT_ a permanent storage area inside the kernel for new connections. Once people writing these apps start thinking about it as a buffer (ie. think "temporary"), the thought to increase SOMAXCONN will occur less often in their minds.
I have never been shown a legitimate argument for increasing SOMAXCONN.

Its pretty meaningless as a value. People who say they need a larger SOMAXCONN are as a general rule simply wrong in the Linux case
