Failed to take photo: PiCameraMMALError

[jnaulty]

Ran into an issue with the /photo command.

Running on a raspberry pi 3+

Not sure if this is related to rpi-security or something in picamera, but posting here first for when I find a proper solution.

a reboot fixed this. uptime was ~8 days

Hi @jnaulty, do you have any other apps on your Pi that use the camera?

[jnaulty]

No other apps that I'm aware of..

[FutureSharks]

What version are you using? When did you install it? Does it do this all the time? Or just some times?
