APAR status

• Closed as program error.

Error description

• Jobs with SCD stages may sometimes appear to hang or fail.
  Stack traces of the hung processes will usually look like this:
  
  APT_KeyLookupUpdatable::APT_BTreeNode::addChild(APT_KeyLookupUpd
  atable::APT_BTreeNode*,APT_KeyLookupUpdatable::APT_BTreeNode*,AP
  T_KeyLookupUpdatable::APT_BTreeNode*&,APT_KeyLookupUpdatable*)()
  at 0x9000000038285d0
  APT_KeyLookupUpdatable::loadTable(const APT_UString&,char*&,long
  long&,bool,APT_ErrorLog&)() at 0x900000003827ca4
