Hi,

Hello all ,
In the compilation of squid ,I used cache_mem 1200 MB cache_dir null
The cache line looks fine, I doubt that is causing you problems
fs.file-max = 16384
That should probably be higher, like 32786 or something higher...
net.ipv4.ipfrag_low_thresh = 900000
net.ipv4.ipfrag_high_thresh = 1000000
net.ipv4.ipfrag_time = 45
net.ipv4.tcp_rmem = 2000000 2250000 2500000
net.ipv4.tcp_wmem = 1000000 1250000 1500000
net.ipv4.neigh.default.gc_thresh1 = 1024
net.ipv4.neigh.default.gc_thresh2 = 4096
net.ipv4.neigh.default.gc_thresh3 = 8192
net.core.rmem_max = 1500000
net.core.rmem_default = 1500000
net.core.wmem_max = 1000000
net.core.wmem_default = 1000000
What the heck? Why are your settings set to such insane levels? The
first number in net.ipv4.tcp_wmem and net.ipv4.tcp_rmem would cause you
problems.
tcp_wmem - vector of 3 INTEGERs: min, default, max
min: Amount of memory reserved for send buffers for TCP socket.
Each TCP socket has rights to use it due to fact of its birth.
Default: 4K
tcp_rmem - vector of 3 INTEGERs: min, default, max
min: Minimal size of receive buffer used by TCP sockets.
It is guaranteed to each TCP socket, even under moderate memory
pressure.
Default: 8K
Taking a wild stab, and saying 256 file descriptors open, that means
something on the order of:
256 * (2000000 + 1000000) = 768 MB (and that is MINIMUM even under
moderate memory pressure)
Lower all of your numbers down to a sane level....
