ulimit_nofile = 2048#

On Unix systems, specifies the minimum desirable value for the RLIMIT_NOFILE soft limit.

That system parameter controls the maximum number of file descriptors that a given process is permitted to open.

On startup, wakterm will inspect the soft and hard limits, and if the soft limit is below the value of the ulimit_nofile option, wakterm will attempt to raise it to min(ulimit_nofile, hard_limit).
