Error description
System crashes with the following stack trace when using automount with -hosts map AND when the NFS server has exported parent and sub-directories. (0)> f pvthread+013D00 STACK: WARNING: bad IAR: 00000000, display stack from LR: 0042F838 [0042F838]vfs_root+000030 (0000000000000000, 0FFFFFFFF3FFF970, F10001001019B37C [??]) [05AD7EFC]auto_perform_actions+000480 (??, ??, ??, ??) [05AD6F68]auto_mount_thread+000198 (??, ??, ??) [00172830]procentry+000010 (??, ??, ??, ??) AIX NFS server does _not_ allow parent and sub-directories to be exported, so this problem does not happen when using AIX NFS server.
Local fix
1. Do not export parent and sub-directories at the same time. OR 2. Use manual mounts instead of automount
Problem summary
host map AUTOFS may crash when NFS server has exported both parent and sub-directories.
Problem conclusion
Ensure directory names are properly tokenized.
Temporary fix
