Error description

• After upgrading the VOB server to IBM Rational ClearCase 7.1.2.3
  importing an update packet with multitool syncreplica may cause
  Microsoft Windows to produce an application error and Unix or
  Linux to produce a segmentation fault.
  
  Windows error
  Popup error message:
  The instruction at ?address? The referenced memory at ?address?
  The memory could not be read
  
  Similar messages will be seen in the Windows Application Event
  Logs.
  
  Unix
  syncreplica -import will fail with a Segmentation fault error
  and a core file will be created.
  
  The error occurs because an oplog's 'event info' is null.
  So far this has only been seen with mklabel operations but it is
  possible that other oplogs may cause this as well.
  
  Verifying the problem
  From a view and vob context run
  multitool lspacket -long -dump ?packet name?
  Where packet name is the packet failing to import.
  
  Search the output for a mklabel operation that is missing the
  'event comment=' section
  
  example:
  12390:
  op= mklabel
  replica_oid= bd9f6920.322a5a64.985d.41:68:70:99:06:e1 (*object
  not found*)
  oplog_id= 5110
  op_time= 2011-07-04T12:20:00Z  create_time= 2011-07-04T12:20:00Z
  data size= 36  data= 0x1058d50
  ?cut?
  
  The event comment is usually found between the op_time and data
  size for mklabel and should look similar to this:
  op_time= 2011-07-04T12:20:00Z  create_time= 2011-07-04T12:20:00Z
  event comment= 'comment'
  data size= 36  data= 0x1058d50
  
  Note: A blank event comment will not cause the problem
  event comment= ''
  
  Note: there may be multiple mklabel operations that do have a
  proper event comment so to quickly test for this issue count the
  number of 'op=' values and compare with the number of 'event
  comment=' instances. If the values do not match, this is most
  likely the issue causing the import failure.
  
  Workaround
  None
