Problem summary


    

  • Justify why this fix is being delayed for a future release
(blank line to stop):  hange is done in complex VFS (Virtual
File System Consistency Manager) , SM4 module, Changes is to do
with File record state flag, hence it would be risky to dropp
changes into service stream, However this issue is reported
only by one customer and it is very rarly recreatable, Will
wait for couple of months before we pull the changes back to
service streams.reported only by one customer and it is very
rarly recreatable, Will wait for couple of months before we
pull the changes back to service streams.
