Hi,

On ubuntu, I tried

su - www-data
ulimit -Hn
>> 200000
ulimit -Sn
>> 100000

The value seems be fine as I have worker_connections = 4000, and
worker_processes = 4, so total is 16000, and still within the limit.

But when my server become busy, I can find the error log contains the line
entries

"..(24: Too many open files),.."

Any way to debug? Thanks..
