Another patch that went in right around that time:
commit 52bf376c63eebe72e862a1a6e713976b038c3f50
Author: John Heffner <[EMAIL PROTECTED]>
Date: Tue Nov 14 20:25:17 2006 -0800
[TCP]: Fix up sysctl_tcp_mem initialization.
(This has been changed again for 2.6.21.)
In the dmesg, there should be some messages like this:
IP route cache hash table entries: 32768 (order: 5, 131072 bytes)
TCP established hash table entries: 131072 (order: 8, 1048576 bytes)
TCP bind hash table entries: 65536 (order: 6, 262144 bytes)
TCP: Hash tables configured (established 131072 bind 65536)
What do yours say?
For the 2.6.19.5, where we have this problem:
From dmsg:
IP route cache hash table entries: 4096 (order: 2, 16384 bytes)
TCP established hash table entries: 16384 (order: 5, 131072 bytes)
TCP bind hash table entries: 8192 (order: 4, 65536 bytes)
#cat /proc/sys/net/ipv4/tcp_mem
3072 4096 6144
MemTotal: 484368 kB
CONFIG_HIGHMEM4G=y
Thanks,
Sincerely,
