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
