Now tell me should I delete /var/cache as it occupies around 127M of the
disk space. In doing so it will create a lot of free space in the /var
partition, but then how good it would be for the cache ??
Will it become too slow as then cache has been removed ?
Ah, /var/cache usually contains the combined caches of many system
services. You can see which ones by "ls -la /var/cache"
The output of ls -la /var/cache is shown below as:
Now tell me which directories should I look on to delete the unwanted files.

The worst problem you have is as I suspected the logs at ~10,000 MB,
next biggest is the /var/spool at ~2,000 MB (which is probably where
squid cache data actually is).
Lets see which of those apps is guzzling space:
du -sh /var/cache/*
my moneys on yum or tomcat.
The following has been observed in the /var/spool. this is as shown below.
It has been observed that most of the files of /var/spool/squid are all
empty except some which are big and they are in machine format (ascii).
If these files are used by the cache to speed up the function of the proxy
whenever it comes across a request from a student.
They look to me like your squid is crashing and burning. Those are core
files, generated by the system on fatal software errors.
Remove the ones of size zero, they are useless. Also any from before
your last squid install upgrade.
For the rest there is a simple procedure to find out why it died so
horribly:
http://wiki.squid-cache.org/SquidFaq/TroubleShooting#head-ec6b316c2f73a72782198dab56d9e9a3a7127eeb
If it shows an "assert" happening, we would be interested in knowing the
squid version where its happening and getting a copy of the trace.
Bug reporting details are on that page I linked.

Find out whats leaving so many of such big logs and see if you can cut
the size down a bit.

yup these files are generated to keep track of the sites visited by the
student users more than 1000, to keep a check on :
they are crated on the directory:
/var/www/sarg/daily
The filenames are of the type:
