now if you notice in time of 12:55:46 there is a invalid request from my client so the access.log file shows a normal http request in this second as shown, kindly at least can you show me a hint about object i can read to solve this invalid request issue,

the queue congestion error because i have three partition (each with 5 GB ) for squid directory in the same hard,and the hard is sata so i think it's a hardware issue,

OSError: [Errno 2] No such file or directory: '/var/log/videocache/videocache.log.10' this error is new i noticed today for the first time i checked the directory and there is file videocache.log.10 (its exist) so what is the cause of the error? please

before two days i have a forward loop warning i solve this problem by changing the iptables rules which is in your book i think it's for proxy becoming the gateway for the network that what i though at least, so you don't need for the rule to drop the packet that comes from the squid box it self, that what i though at least, can you correct to me the information if it's wrong please,
my squid is installed on ubuntu server 11.04,

caching is working normally but i think this problem effect for the squid server performance

thank you with my best regards i hope you have the time to answer me

Hi,

Your Squid is overloaded because of heavy I/O. Try to get a faster disk. If it's not possible to get a faster disk, try disabling Squid's cache and check the performance again. The warnings are not severe and are related to videocache's log rotation mechanism.
