Error description

• Tivoli Storage Manager server will crash if an Administrative
  Schedule attempts to write data to a file that the server does
  not have the correct permission.
  
  Customer/L2 Diagnostics:
  Example of Admin Schedules:
                    Schedule Name: INSTRBEGIN
                      Description: Instrumentation trace
                          Command: instr begin
                      ...
                    Schedule Name: INSTREND
                      Description: Instrumentation trace
                          Command: instr end file=/tsmserver/
                                   instr/instr.out
       ...
  The problem is the OS file permission for the directory did not
  allow the server instance owner account to access this output
  file.
