[quagga-users 14006] ISISd consumes 100% CPU

Hi,
I'm running quagga 0.9.24 on Ubuntu12.04. The Adjacent router is a 
JUNIPER EX-series running both ISIS and OSPF.
Recently I've noticed that some hosts connected to the Juniper are not 
reachable due to the fact that the route towards them does not exist.
During such periods (before I restart the quagga service), I've also 
noticed that the ISISd consumed 100% CPU (as indicated by 'top')
Is there a known issue related to this?
Anything I can do to limit CPU consumption?
I'm attaching a fragment of the ISISd syslog, if it will help...

Thanks!
