Hello,
Given the amount of memory and the amount of swap, you probably
run into a shortage of memory/swap in total. I saw similiar
problems on a old computer which had almost the same amount
of memory, it would run out of those things pretty quick, especially
when building heavy material like MySQL etc.
Please do note from a security point of view that 6.0-R is no longer
being supported, please ponder upgrading to 6.2-R.
Cheers,
Remko
p.s. With this explaination i will close this ticket.
