How many ncftpd processes will be running simultaneously?
There will always be min-users + 2 processes, upto a maximum of max-users + 2 processes. In other words, there is one process that serves as the master process, one responsible for logging, and one process for each user being serviced. Dont be alarmed by a large number of processes if you have min-users set relatively high. Processes not actually running will be swapped out and will not consume system resources.
