FATAL: sorry, too many clients already

I started getting this error when trying to load webodm this morning. any idea what causes it, how do i recover from it, and how do I avoid it in the future?

WebODM is installed Native on Ubuntu using the paid server installer.

thanks in advance for any help.

Mm, this could be a bug. Could you open an issue on https://github.com/OpenDroneMap/WebODM/issues? What happens if you restart the server? Also, how long has WebODM been running?

Oh, and are you on version 1.0.2? Make sure you are not on 1.0.1! Do not use WebODM 1.0.1, upgrade to 1.0.2

i will reboot and run the installer to make sure i am not on 1.0.1. the server had been up for about a month. if it comes back after that i will open a case.
