3088292 - A query having a view which references a table with the same name may get into infinite loop -- SAP ASE


  • Query references a view which select from a table with the same name and different owner.
  • The query takes high cpu time (pss->pcpucur) and high memory pages from procedure cache memory pool (pss->pmemusage).
  • Normal ‘kill spid’ doesn’t work, need to use force option ‘kill spid with force’.
  • Drop and recreate the view may work again.
  • May get into the problem again when reload database or ASE upgrade.
  • Samples of ‘dbcc stacktrace(spid)’ for the looping process may include routine names: vu_viewcopy and memalloc.
