Hello,
I found my squid server offten reaches out of file descriptor.
Of course, I can change the FD value to increase it.
At the time, I also check "Process Filedescriptor Allocation"
by Cache Manager. There are many half-closed file descriptors
occured from one same IP, please read the following contents
from Cache Manager:
Active file descriptors:
File Type Tout Nread * Nwrite * Remote Address Description

I think this may be an error or bug. I don't know what this meaning is.
Can we resolve this? This matter decreases the efficiency of squid server,
it uses many file descriptors so that others cannot use them.
159.226.185.105 is one of our clients. Our IP address is from 159.226.171.0 to
159.226.186.255. 159.226.236.0/24 is also our IP address.
