Hi Jan,

thanks for the reply, sure, I'll gather and post requested info.
One more note before that, the problem is with psacct, not audit
 - psacct if I'm not mistaken  (and as opposed to audit) doesn't
use any userspace, kernel dumps information directly to fs, 
which might the reason for deadlock..
