After updating iptables won't start:
[root ~]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: Another app is currently holding the xtables lock. Perhaps you want to use the -w option?
[FAILED]
Using -w option won't help.
***
Only thing that helps is to downgrade iptables.
