High load, lot of zombies (150+) spamassassin

[asmar]

Hello,

As soon as I start spamassassin the load goes up to 2-6 and zombies are always more than 150.
I've upgraded exim to the latest version but problem remains.
This is happening only when I enable spamassassin.
When it is disabled then load is 0.02 and zombies 0.

Any ideas?

Thanks

Do you have any users who are using more than 100% of their diskspace?
If so, do they receive a lot of e-mails?

Could you do an strace on the zombie processes?

Would you please elaborate on strace. What exactly should I do.
Users are not using 100% of their space.

Thanks
