Hello,
I've been doing some experiments today and noticed RB333's strange behaviour with 2 bridged EoIPs. Configuration was like that:

Bridge1 : {EoIP1, EoIP2, wlan1, ether1} + some Filter rules related to EoIPs

When i enable in /interface both EoIPs, system restarts every 1-2 min. With one EoIP everything is ok. I can provide supout.rif file.

MikroTik version 3.0rc14 and 3.0

Send the supout.rif to support@mikrotik.com. That way you get faster response to your issue.
