[squid-users] Strange RST packet

[Luis Daniel Lucio Quiroz]

After debuggin,

I've found that squid is sending a RST packet to a Windows station (WinXP SP2 
or WinVista).

Squid is not configured to send RST's.  Is there any explication for this?

Regards,

LD

Are you sure that the client is connecting to the correct port and that the 
service is running? The OS will typically respond to a SYN on a closed port 
with an RST.

I'm pretty sure.

I have a pcap file captured and, traffic is exchanged and then suddenly a RST 
from squid to client.

(From memory, check the code to be sure .. )
In HTTP RST is used to signal incomplete transfer of dynamic content;
its quite likely that the upstream server has done a RST to squid, and
squid is passing this on.

No FIN before?

What is the situation?

Do other clients work OK ?

Did you check if Squid crash occur (check in cache.log) ?

I there a specific scenario leading to RESET ?

Squid doesn't send RESET without reason, check for reason in capture
