I recommend Squid upgrade if possible due to couple bugs as something..
Try to bump the server to 32k open file descriptors and see what
happens.
Depends on the load on the server it might need at peek times more then
8k.
The cache manage info page should give you couple technical details on
the status of the service.
It can also give some statistics which might shed some light on the
scenario.
Others might be able to give you some more detail on the relevant cache
manager pages.

Hello Squid Group,
I am using squid 3.5.20 as a proxy server. I Increased the memory
from 12 GB to 32 GB and Max file descriptors from "4096" to "8192" and
deployed this server into production on 09/26/2018".
I don't have any problem from the past 10 days everything working as
expected till today. Now after 10 days for the first time, I got
following errors on cache log today. Can someone advise/suggest any
ideas here?
