mysql and oom-killer

[Евгений Килимчук]

Hello!

I use CentOS 5.4 with LAMP. On the server runs heavy cgi-programs. MySQL use
75% (100% = 8GB) of memory. When cgi programs use more than 25% of memory
and all SWAP file (8GB), kernel run OOM-Kiler wich kill mysqld procces.

I use:

echo "0" > /proc/sys/vm/swappiness - This allows to reduce using of  SWAP.

I want to use:
echo "-17" > /proc/`pidof mysqld`/oom_adj - This allows save mysqld when run
oom-killer.

Someone used this option?
