Zooming out on Montage Review (or panning left) gives blank screen

Hey Folks, I have an entirely "out of the box" Ubuntu Bionic with 36.11 with no customizations or anything... all runs GREAT for weeks but if I try and pan left or zoom out past three days in Montage Review I get a blank white screen in my browser. I've 9 cameras (3-6fps) doing a mix of modetect/record/mocord etc. and load varies between 0.9 and 2.9. The machine is an i7, 16gb ram with 8TB, 3TB and 2TB drives storing the video running the standard Purge filter. A 128GB SSD accommodates the system, the database and whatnot.
Same issue Edge/FIrefox/Chrome, etc. Or if I click "ALL EVENTS." HTTP ERROR 500
Thanks in advance for any tips!

You are running out of ram for the php process. By default is is 128M. Edit /etc/php/apache2/php.ini and change the memory limit setting.

thanks... in the ini today I have this:
; Maximum amount of memory a script may consume (128MB)
;
http://php.net/memory-limit
memory_limit = -1
Not sure what -1 means (no limit?) but I will try fiddling with some different values. Not sure if this is an applicable question but what is a reasonable value for 9 cameras at a moderate frame rate? And is this related to my system memory in some way?
thanks for any guidance...

hey I tried a variety of GB RAM values (rebooting as I went) but I still get the blank page/500 error after a few pans left or zooming out.
What values do you use in your ini file? Also is there a way I can verify if ZM is struggling with memory? (I have 16gb)
"All events" still always throws 500 error.

any thoughts appreciated regarding memory settings (?), i really cannot go back more than a few days using "PAN" without 500 error. DItto for Zoom out
Everything is out-of-the-box ubuntu server and 36.11 (fresh install, not upgrade) SHould I go to .12?

If you specified a GB limit, then I would be very surprised if you ran out of ram.
I suspect you DIDN'T. Because maybe php doesn't understand your units, or someting.
memory_limit = 1024M
You will need to restart apache2 after making the change.

Hey thanks for that. I can now Pan Left about 11 days, which is very helpful!
Side note: I wonder if I am using the tool wrong still because if I try and use the date range picker (say 10 or 11 days earlier; through to present day) I get the 500 error. Ditto if I try Zoom out or All Events. Does that happen for you too?
