Jeffrey, First go to the ORACLE_HOME used by your nodeapps (probably the database or the asm home, not crs. I believe that changes in R2). You can add additional logging by editing $ORACLE_HOME/opmn/conf'/ons.config and setting 'log level=3'. Then check out $ORACLE_HOME/opmn/logs and also $ORACLE_HOME/racg/dump. Probably a good idea to check these even before editiing ons.config. Hopefully your errors will show up here.

I'm currently running a 10.1.0.4 two node RAC instance (RHAS 3 Update 4) using Polyserve for the Shared Oracle Home. The ONS keeps on terminating on one of the nodes after the nodeapps have been restarted, however the ONS on the other node has no problem. Thanks JPD
