[squid-dev]Epoll Squid Test on Ia64

Hello all ..,

                   Thank you Developers for the nice Reply to me.

I have tuned the File-max to 32768 and changed the cache_mem 64 MB.
Then I have changed the kernel parameters as

net.ipv4.ipfrag_low_thresh = 196608
net.ipv4.ipfrag_high_thresh = 262144
net.ipv4.ipfrag_time = 45
net.ipv4.tcp_rmem = 4096 87380 174760
net.ipv4.tcp_wmem = 4096 16384 131072
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 = 65535
net.core.rmem_default = 65535
net.core.wmem_max = 65535
net.core.wmem_default = 65535

But this time also I am getting some messages in /var/log/messages as

Sep 5 17:20:53 pandia squid[1440]: Squid Parent: child process 1442 started
Sep 5 17:21:05 pandia kernel: squid(1442): unaligned access to

Sep 5 17:24:29 pandia squid[1452]: Squid Parent: child process 1454 exited
with status 255

I am getting so many "Squid Parent:child process 1454 exited with status 255
and etc." in the /var/log/message.

In the first while using the parameters as
net.ipv4.neigh.default.gc_thresh1 = 128
net.ipv4.neigh.default.gc_thresh2 = 512
net.ipv4.neigh.default.gc_thresh3 = 1024

I got the messages as Squid Parent: Child exited due to signal 6.
Then I have tuned that parameters.Then there is no messages like "exited due
to signal 6" in the log.

So please give the correction on the Kerenl parameters in the above.

Squid Server
                Processor : Dual Itanium 2 900MHz
                Memory: 2 GB
                OS: RedHat Advanced server 2.0
                Kernel: Kernel-2.4.20
                Squid: squid-3.0.PRE3
Polygraph Server
                Processor : P III 930MHz
                Memory: 512 MB
                OS: RedHat Linux-7.3 and RedHat
Linux-8.0
                Kernel: Kernel-2.4.20
                Polygraph: Polygraph-2.55
Query:
# Then another query that anybody tested the squid with epoll support on
IA64 more than 300 requests,
Please suggest your memory consumption,kernel version and kernel parameters
and kernel usage for testing.
# Anybody checked the squid-3.0 for epoll in kernel-2.6 kernel.
I have tried a lot to compile the kernel ,but because of assembler,compiler
and linker,I couldn't make it.If anybody did that on IA64 then please give
the info
about that also.

Caching the replies from Developers ....,
