[root at serv root]# wc -l /proc/net/ip_conntrack
    368 /proc/net/ip_conntrack
[root at serv root]# ps -ax|grep oidentd|wc -l

And both are inrcreasing until machine hangs. Request was received from 
remote server and 'netstat -anp' shows a lot of entries like the one 
tcp       29      0           
ESTABLISHED 25966/oidentd

I got confused by those local connections, and now I really don't know if 
this is normal behaviour or not. But this is happens only on oidentd 2.x.
Switching back to oidentd 1.x fixed the problem.
