And what does this 503 page content??
I do not know what the issue in hands is but there are couple things to
first test before running into full debug or try to fix issues that
might not exists.
The version upgrade is there for a reason.
I do know why an upgrade might not solve the issues but still if you
have testing environment try to make sure what are the results with the
latest 3.1.X branch which should be 3.1.21 if I am not wrong.
It is very critical for you to test it.
Since squid can run on many OS and many specs your logs are nice but not
helping to understand the whole issue.
There are many bugs that was fixed from the 3.1 list but I have used it
for a very long time.
If you need help installing 3.1.21 or any newer version I can try to
assist you.
Also it can be installed alongside another version.

Hi Eliezer/All,
Thanks for your help.
PFA log snippets.
Log1.txt is having sample 1 of cache.log in which you can find the time gap.
Log2.txt is having sample 2 of client output and cache.log showing the time gap.
It seems that there is some in memory operation "StatHistCopy" which
is causing this issue, not sure though.
Squid version is: Squid Cache: Version 3.1.6.
Please let me know that if these logs are helpfull.
Thanks & Regards,

Hey,
Can you try another test?
It is very nice to use wget but there are couple options that needs to be
consider.
Just to help you if was not there until now add: --delete-after
to the wget command line.
It's not related to squid but it helps a lot.
Now If you are up to it I will be happy to see the machine specs and OS.
Also what is "squid -v" output?
Can you ping the machine at the time it got stuck? what about tcp-ping or
"nc -v squid_ip port" ?
we need to verify also in the access logs that it's not naukri.com that
thinks your client is trying to covert it into a DDOS target.
What about trying to access other resources?
What is written in this 503 response page?

Hi,
I enable the logging but didn't find any conclusive or decisive logs
so that I can forward you.
In my testing, I am accessing same URL 500 times in a loop from the
client using wget.
Squid got hanged sometimes after 120 requests ,sometimes after 150
requests as:
rm: cannot remove `index.html': No such file or directory

Whenever it got hanged, it resumes after 1 minute e.g in above example
after 03:52:37 the response came at 03:53:39.
Please provide more help.
Many Thanks,
