Closed as program error.
Error description
When a file is accessed in a CIFS mount while that file system is also being unmounted, AIX can sometimes crash with a stack trace similar to this: [00406F3C]bad_vnode_bad_caller+000000 (F1000100450B4880 [??]) [0040C874]vnop_getattr+000118 (??, ??, ??) [0044B128]getstat+000020 (??, ??, ??, ??) [0044BCA4]fstatx+0000F4 (??, ??, ??, ??) [00003810].svc_instr+000110 ()
Local fix
The workaround is to unmount CIFS file systems as infrequently as possible.
Problem summary
VFS assert because CIFS vnode/gnode freed while in use.
Problem conclusion
Put in place proper synchronization mechanism to prevent any currently used vnode from getting freed.
Temporary fix
