2298521 - In IQ16 SP10.11, 's_dpidx.cxx' was detected in consistence index checking.

After installed SP10.11, a delete query encountered 's_dpidx.cxx:7241' error.
  While deleting, two indexes were detected problem in allocation pages.
  It's not sure if the table has been damaged or it was fine before the s_dpidx error.
 
  DBA ran DBCC after the erro, but **_ITR_DY' checked as 'No error detected'.
  After the delete job, in SP10.11, server detected the 's_dpidx.cxx' in index verification phase
  and let the changes by delete job be rollbacked.
