Hi,
Our 2 nodes RAC worked for over 6months without any problems. Suddenly both the 2 nodes crashed with error "BUG: soft lockup - CPU#11 stuck for 67s! [migration/0:5]" in the console.
We are with Oracle CRS/RAC 11.2.0.4 in Redhat 6.3. Kernel used is 2.6.32-279.el6.x86_64. Both the 2 nodes are HP ProLiant DL380p Gen8 with BIOS P70 03/01/2013. The shared storage is NetApp and NFS is used.
After re-booting the RAC is back to normal. I wonder if this can happen again and how to prevent such incident (upgrade Kernel/BIOS etc)?
Pls advice.
Pham
