Unhappy Mysql and EOPNOTSUPP process

Hello, Its my first post in this forum.

My problem is that I have a constant mysql process using 10-20% CPU, its very strange because the process is always present, if I restart apache and mysql and I just open the phpmyadmin or any website connecting to the DB I get this error.

With strace I have seen tha tthe process details are:

futex(0x87326c4, 0x5 /* FUTEX_??? */, 1) = 1
futex(0x8732174, FUTEX_WAKE, 1)         = 1
select(15, [13 14], NULL, NULL, NULL)   = 1 (in [14])
fcntl64(14, F_SETFL, O_RDWR|O_NONBLOCK) = 0
accept(14, {sa_family=AF_FILE, path="ӿ"}, [2]) = 25
fcntl64(14, F_SETFL, O_RDWR)            = 0
getsockname(25, {sa_family=AF_FILE, path="/var/run/mysql"}, [30]) = 0
fcntl64(25, F_SETFL, O_RDONLY)          = 0
fcntl64(25, F_GETFL)                    = 0x2 (flags O_RDWR)
fcntl64(25, F_SETFL, O_RDWR|O_NONBLOCK) = 0
setsockopt(25, SOL_IP, IP_TOS, [8], 4)  = -1 EOPNOTSUPP (Operation not supported)
The strace show that this piece of code is being repeated everytime that any website or app is using the database.

Server specs:
CENTOS Enterprise 4.6 i686
Linux 2.6.9-67.0.7.ELsmp
Core2Duo E6750
PHP Version 5.2.5
MySQL 5.0.45

Anybody know how to solve it?

Thanks in advance
