Last updated on OCTOBER 20, 2011

Applies to:

Oracle Server - Enterprise Edition - Version: 11.2.0.2 and later   [Release: 11.2 and later ]
Information in this document applies to any platform.

Symptoms


3 nodes RAC - 11202+ no PSUs (ASM/DB) - OEL5

As soon as they start seeing the ASSERTION FAILURE for ACFS from node3's messages file, all access attempts to the ACFS file system hangs (i.e., ls,df,cd,etc.) from all 3 nodes in the cluster

The OS messages show these "ASSERTION FAILURE: (size_t)size <= max File: /scratch/builds/aime/aime_usm_758305/usm/src/oks/driver/./lin/ks0.c Line: 700" entries every time the ACFS file system freezes:
