[SQU] Invalid Request Again.

Hi all,

I've 3 proxies running as peer, all are running squid2.2stable2 as a
transparent proxy. Recently, there are user report that sometimes they
can't browse some page unless they press the reload button. The error
message is something like:

While trying to process the request:

ERROR

More information in access.log:

972560151.170 5 137.189.126.247 NONE/411 1788 GET
http://www.ebabyasia.com/admin/misc/classified/cla_admin.asp - NONE/- -

However, there is nothing I can found in cache.log

Is there any information about this problem, I've lookup some old archieve
in the mailing-list but I can just found some similar thread, I'm not sure
whether this is the same problem as before.

I can just found in squid-cache.org that the result code NONE means "Seen
with errors and cachemgr requests." However, I can't found further
information that why this happen...

Anyone can help?? Thanks in Advance.
