Waybar reaches file descriptor limit in Alpine Linux.

[mubin-thinks]

I've recently moved to Alpine Linux. I'm using Waybar with SwayWM. Waybar does not get autostarted by Sway and When running waybar through command line the file descriptor limit error is shown.

I've tried to increase the limit to 4096 with ulimit -n 4096(maximum possible) and looking at /proc/sys/fs/file-nr, waybar slowly uses all the 4096 file descriptors. That is weird.

Here is the output of running waybar the terminal:
