Many ORA-7445 [kfclDumpLe] errors get reported in ASM alert log, usually on one node only, and the errors are logged in ASM DIAG trace file.  Incidents are also generated with DIAG incident trace files.

No ASM instances crash and no database instances crash.

ASM alert log would typically have the error reported as follows (multiple times):

Exception [type: SIGSEGV, Address not mapped to object] [ADDR:0xE000000A8] [PC:0x1053E755C, kfclDumpLe()+02fc]
Errors in file <diag dest>/asm/+asm/+ASMN/trace/+ASMN_diag_nnnnnn.trc (incident=iiiiii):

ped to object] []
Incident details in: <diag dest>/asm/+asm/+ASMN/incident/incdir_iiiiii/+ASMN_diag_nnnnnn_iiiiiii.trc



ASM DIAG trace/incident file would typically have the following:

Dump continued from file: <diag dest>/asm/+asm/+ASMN/trace/+ASMN_diag_nnnnnn.trc
ORA-07445: exception encountered: core dump [kfclDumpLe()+02fc] [SIGSEGV] [ADDR:0xE000000A8] [PC:0x1053E755C] [Address not mapped to object] []
