Symptoms


3 nodes RAC - 11202+ no PSUs (ASM/DB) - OL5

As soon as 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: /<DIR>/aime/aime_usm_758305/usm/src/oks/driver/./lin/ks0.c Line: 700" entries every time the ACFS file system freezes:
