Can't have more than 5 monitors active?

[Chimaera]

I have a new Pi 4 running Buster with ZM 1.32.3. I'm using a bunch of Amcrest cams over RTSP and they work fine until I try to add the 6th monitor, which won't come up (errors below). If I remove a previously working monitor, the new one comes up. Try to add a 6th, same issue. Doesn't matter which order or which substreams, it's always 5 works then 6th fails.

I had this working in a virtual Centos 7 box without issue, with less ram (2gb vs 4 on the Pi) so I don't think it's that. Any ideas???

You are out of memory in tmpfs AKA /dev/shm. With a Pi you should feel lucky to get one camera to run.

Also, set Zoneminder to capture .jpgs and turn off video storage.

And your API will not work as there is a problem with Buster that has not been solved...yet.

[Chimaera]

API is working fine, other than notifications. I can use ZMninja but not get push notifications. Video storage is on a NAS over ethernet not the Pi so speed isn't an issue there.

Pi 4 has 4gb ram, more than my Centos 7 VM had so /dev/shm should be fine too, it's 2gb with 1.5gb free.
