Well it happens that 8GB of memory will not be enough for 240GB of ufs
disk cache as far as I can tell.
Lets try to fix it one step at a time.
Since you are getting into a position which squid get's stuck we can go
from step A to B and then to C.
First decrease the number of ufs directories to something like 1...
The cache_dir can handle more then what some can imagine.
What is the cache_dir number of objects?
You can use the cache_mgr interface to get some statistics on the cache_dir.
It's version 3.1.20 so basically you should be able to access it using
"squidclient mgr:menu"
I do not remember the exact name but it has something about the cache_dir.
After you will have one cache_dir which fits your number of files in a
form of for example 64 top directories and 256 upper directories you
might see something else.
note that 50M (million right?)json objects are huge but you might have a
limit from the INODE limit of the FS way before squid limits.
The machine basically doesn't meet the basic specs to store 50Million files.

Hi Eliezer,
Thanks for your response, please find the answers below.
what are the machine specs?
Machine on which Squid is running, is VM having 2 cores and 8 GB of memory.
why are you using so many ufs cache dirs? is there a reason?
Yes, our purpose is to cache more than 50M json objects.
Tried running with single cache directory. that didn't work,
after 10-15 days Squid will stop responding with below error in
cahce.log.
"assertion failed: filemap.cc:76: "fm->max_n_files <= (1 << 24)"
I came across work around for the above issue on internet, that
mentioned having multiple cache directories.

Mainly this squid version is old and I suspect it's not supported anymore.
64 doubles 5.1 is above 240GB of cache which requires lots of memory.

Hello,
I am running squid as http caching server, after running for few days
our squid server will stop responding to client requests.
When this occurs, I see below errors in cache.log.
