[LON-CAPA-admin] httpd: Unit:: messages in /var/log/messages

We're running LON-CAPA 2.11.3-2021031720 on CentOS 7.  We recently 
upgraded from 2.11.2 to 2.11.3 and are starting to see heavy use again 
with the new school term.

We seem to be experiencing some load related problems after the 2.11.3 
upgrade that I don't recall us having last year with 2.11.2.  When this is 
happening I am unable to login as Domain Coordinator and monitor Status 
Information.

Other than the 2.11.3 upgrade, and installing all other outstanding CentOS 
7 updates, nothing has intentionally changed with this LON-CAPA server.

While doing some initial diagnosis of this performance problem, I happened 
to notice that messages like the following are regularly being written to 
/var/log/messages on our LON-CAPA server.

Sep 12 14:23:14 loncapa01 httpd: Unit::[m] = 1 * (1*m^1) (1*s^-2)
Sep 12 14:23:16 loncapa01 httpd: Unit::[cm] = 0.0001 * (1*m^2)
Sep 12 14:23:19 loncapa01 httpd: Unit::[deg] = 0.0174533 *
Sep 12 14:23:19 loncapa01 httpd: Unit::[kg] = 1 * (1*m^-3) (1*kg^1)

I have no idea if this is related to our performance problem, or if it is 
some other insignificant problem, but it is unusual and not something I 
would expect to be finding, neither from httpd nor in /var/log/messages. 
If for no other reason, I'd like to eliminate thes messages since they're 
just log noise consuming disk space.

Any ideas?

Thanks,
Todd
