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: Core Group: MonetDB5 CVS Head Status: Open Resolution: None Priority: 5 Private: No Submitted By: Stefan de Konink (skinkie) Assigned to: Nobody/Anonymous (nobody) Summary: Double free error Initial Comment: The following output I saw on my screen; I don't know how to reproduce it yet. And this not the latest head. Still I hope the backtrace could be useful to debug the issue. I am running the database now in valgrind, and as far as I know only one query is fired upon it. skin...@productie ~ $ /opt/monetdb-head/bin/mserver5 --dbinit="include sql; sql.start();" --dbname=monitor --readonly --set mapi_port=50001 # MonetDB server v5.17.0, based on kernel v1.35.0 # Serving database 'monitor', using 4 threads # Compiled for x86_64-unknown-linux-gnu/64bit with 64bit OIDs dynamically linked # Detected 3.856 GiB (4140695552 bytes) main-memory. # Copyright (c) 1993-July 2008 CWI. # Copyright (c) August 2008-2009 MonetDB B.V., all rights reserved # Visit http://monetdb.cwi.nl/ for further information #warning: please don't forget to set your vault key! #(see /opt/monetdb-head/etc/monetdb5.conf) # Listening for connection requests on mapi:monetdb://127.0.0.1:50001/ # MonetDB/SQL module v2.35.0 loaded >select * from sta^?^?^?^?^?^?^?*** glibc detected *** >/opt/monetdb-head/bin/mserver5: double free or corruption (!prev): >0x00000000064de650 *** ======= Backtrace: ========= /lib/libc.so.6[0x7fee456eb258] /lib/libc.so.6(cfree+0x6c)[0x7fee456efd0c] /opt/monetdb-head/lib/libbat.so.1[0x7fee478dc283] /opt/monetdb-head/lib/libbat.so.1(GDKfree+0x46)[0x7fee478dc30c] /opt/monetdb-head/lib/libbat.so.1(HEAPfree+0x39)[0x7fee478192d0] /opt/monetdb-head/lib/libbat.so.1(BATclear+0x4fd)[0x7fee47a875fd] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so[0x7fee36332d7b] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so[0x7fee36332de6] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so(sql_trans_clear_table+0xef)[0x7fee36324c6d] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so(sql_session_reset+0x89)[0x7fee363276a9] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so(mvc_reset+0xe2)[0x7fee362df592] /opt/monetdb-head/lib/MonetDB5/lib/lib_sql.so(SQLinitClient+0x168)[0x7fee36299c20] /opt/monetdb-head/lib/libmonetdb5.so.5[0x7fee483b9668] /opt/monetdb-head/lib/libmonetdb5.so.5[0x7fee483b96d1] /opt/monetdb-head/lib/libmonetdb5.so.5(runScenario+0x3e)[0x7fee483b9989] /opt/monetdb-head/lib/libmonetdb5.so.5(MSserveClient+0x108)[0x7fee4837473d] /lib/libpthread.so.0[0x7fee4660f2c7] /lib/libc.so.6(clone+0x6d)[0x7fee4574938d] ======= Memory map: ======== 00400000-00405000 r-xp 00000000 08:03 69774938 /opt/monetdb-head/bin/mserver5 00604000-00605000 r--p 00004000 08:03 69774938 /opt/monetdb-head/bin/mserver5 00605000-00606000 rw-p 00005000 08:03 69774938 /opt/monetdb-head/bin/mserver5 00606000-00610000 rw-p 00000000 00:00 0 01aff000-06c44000 rw-p 00000000 00:00 0 [heap] ... ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2873758&group_id=56967 ------------------------------------------------------------------------------ Come build with us!
