php-mbstring module is recommended for install by default.
Anyway after NY I will check this library (phpfastcahe) for use without this module.

I think I fixed it. As usual, I went back and looked at the install docs. It seems they have changed since I had installed on Deb 10. When I checked the packages, php7.3-bcmath php7.3-curl php7.3-mbstring were missing. I installed them and it’s working now. (mbstring probably being the fix).

Hi Adam,
I ran this
sudo svn --config-dir /home/jstanford/.subversion update /opt/observium
&& /opt/observium/discovery.php -u
and it took me to the latest release. discovery and poller are both
erroring out with the same error. I haven’t rolled back the code yet in case you needed me to test something.

You might have omitted the context of what you updated, and from what.
Don't use phpfastcache, it's sort of pointless.
