[squid-users] Squid DNS Issues

Hey,
I have squid version 3.1.9 working as a web forward proxy serving
close to 500 users with over 54000 requests every other day.
However, of recent, it is failing to communicate with the DNS Server
completely which leads to few requests being completed.
This has led to a long queue as to the requests supposed to be
completed which later causes squid to hang.
Shifting the very users to another squid cache causes similar
problems. What could be the issue here?
Some of the errors generated in the cache.log are here below:
getsockopt(SO_ORIGINAL_DST) failed on FD 128:
squidaio_queue_request: WARNING - Queue congestion
urlParse: URL too large (12404 bytes)
statusIfComplete: Request not yet fully sent "POST
http://person.com/ims.manage.phtml?__mp[name]=ims:manage&action=bugreport&js_id=47&"
 WARNING: unparseable HTTP header field {Web Server}

 Any help is appreciated.
