https://bugzilla.novell.com/show_bug.cgi?id=407552 Summary: tar crashes with assertion in io.c:234 Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: R.Vickers@cs.rhul.ac.uk QAContact: qa@suse.de Found By: Customer Since upgrading to opensuse 11.0 from 10.2 backups have been sometimes failing on one system with the message: gtar: io.c:234: ber_flush2: Assertion `( (sb)->sb_opts.lbo_valid == 0x3 )' failed. sendbackup: error [dump (8236) /bin/tar got signal 6] This looks extremely similar to an Openldap problem reported (for example) at https://bugs.launchpad.net/ubuntu/+source/openldap2.3/+bug/215904 http://www.openldap.org/its/index.cgi/Incoming?id=5525;page=1;statetype=1 /bin/tar is from tar-1.19-35.1 and is being invoked by the Amanda backup software thus: running: /bin/tar: 'gtar' '--create' '--file' '-' '--directory' '/home' '--one-file-system' '--listed-incremental' '/var/lib/amanda/gnutar-lists/berlin_home_0.new' '--sparse' '--ignore-failed-read' '--totals' '--exclude-from' '/tmp/amanda/sendbackup._home.20080709031221.exclude' '.' /home contains 172 GB of data.

Neither does the function ber_flush2 exist anywhere in the code. The function is part of liblber from the openldap2 package. So, I am assuming this is an openldap2 problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

To ensure our data was backed up I switched to using dump instead of tar, but I will try configuring Amanda to use dump and tar in parallel on the same data.

I now realise that this bug is quite pernicious, for example it causes dbus and gdm to crash every day or so, as well as Alpine. SuSE 11.0 has been much less stable than earlier SuSE releases, and I am beginning to wonder how much is caused by this one bug. Most demons don't generate any stderr, so this bug could be occurring without anyone realising it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You'll will need an OpenLDAP server with the database suffix "dc=suse,dc=de" (alternatively you can adjust the "dc=suse,dc=de" string in the testcase programm). That server should allow anonymous searches and should have at least some data in it. Mine had around 1000 entries. To reproduce the problem you need the stop and start the server in a loop. I did the following on a console: linux-5uct:~ # while ( true ); do rcldap stop; rcldap start; done (Note: don't use "rcldap restart", as that might take to long) On another terminal you need to start the testprogram. That will run in an endless loop until the crash occurs.

The testcase programm produces a HUGE memory leak. So it will fail at some point. On my test system this point is reached pretty soon (in usually less than a minute). 2. Sometimes the programm gets stopped due to a SIGPIPE it gets delivered. But this is the expected behaviour. The testcase is not written carefully enought to handle that. As long as the testcase doesn't fail with the assertion failure message pasted below anymore I'd consider this bug fixed: io.c:234: ber_flush2: Assertion `( (sb)->sb_opts.lbo_valid == 0x3 )' -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
