I have a 2 nodes Oracle RAC cluster (Oracle Version 188.8.131.52) with nodes let's call them host1 and host2 (2 different LPARs) - OS is AIX 184.108.40.206 64 Bit.
On 25th march 2013 about 1:37 o'clock the node host1 sent a reboot to node 2 (host2) because host1 could not reach host2 via rac interconnect (network is ok and was available).
Now I'v made a nmon analysis and host2 shows that there is no more real free memory on host2 before reboot on 1:37 o'clock. Can this be a cause that host1 cannot reach host2?
Attached is the nmon Report from the rebootet LPAR. (Format Excel 2007).
Thanks in advance for some hints/advice.

Did your host2 makes paging space?
Did you check errpt?
I'm not an Oracle Expert but it seems main problem is host2's memory and i think Oracle RAC communication of 2 node won't use all your host2 free memory...
