Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: PF/runtime Group: Pathfinder CVS Head Status: Open Resolution: None Priority: 5 Private: No Submitted By: Jan Rittinger (tsheyar) Assigned to: Nobody/Anonymous (nobody) Summary: XQ: following step kills Mserver (after 2h) Initial Comment: Running the attached query on a MBench generated XML file (sf=0.1, name=mbench0.1.xml) kills the Mserver after a long, long time with a Segmentation fault. (Using -d10 doesn't change a thing.) The reason either is the missing loop-lifting of the following step or the very large intermediate result (#ctx=2093, #nodes_in_doc=203089). Afterwards the database BACKUP is broken: !ERROR: force_move: link(bat/BACKUP/542.desc,bat05/542.desc)=-1 !OS: No such file or directory !ERROR: force_move: link(bat/BACKUP/544.desc,bat05/544.desc)=-1 !OS: No such file or directory !ERROR: force_move: link(bat/BACKUP/603.desc,bat06/603.desc)=-1 !OS: No such file or directory !ERROR: force_move: link(bat/BACKUP/553.desc,bat05/553.desc)=-1 !OS: No such file or directory !ERROR: force_move: link(bat/BACKUP/554.desc,bat05/554.desc)=-1 !OS: No such file or directory !ERROR: force_move: link(bat/BACKUP/570.desc,bat05/570.desc)=-1 !OS: No such file or directory !ERROR: BBPrecover: recovery failed. Please check whether your disk is full or write-protected. !FATAL: BBPinit: cannot properly process bat/BACKUP. Removing folder BACKUP helps. ---------------------------------------------------------------------- >Comment By: Stefan Manegold (stmane) Date: 2007-02-07 17:42 Message: Logged In: YES user_id=572415 Originator: NO Is the query one of the standard MBench queries? If so, which one? The "milprint_summer" version is known to have problems with MBench queries qa04, qj01, qj02, qj03, qj04; cf., http://monetdb.cvs.sourceforge.net/monetdb/pathfinder/benchmarks/MBench/Tests/All?view=log#rev1.2 http://monetdb.cvs.sourceforge.net/*checkout*/monetdb/pathfinder/benchmarks/MBench/Tests/All Of course, Mserver should not segfault, but (at most) "fail properly"... Did you check/watch how big does your Mserver grows (grew) before crashing? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=1654317&group_id=56967 ------------------------------------------------------------------------- Using Tomcat but need to do more?
