[Virtuoso-users] Segmentation fault while bulk loading

Dear all, I am trying to bulk load rdf named graphs in virtuoso. I obtained the latest version of virtuoso 7.2 using: git clone git:// github.com/openlink/virtuoso-opensource.git The size of my named graphs file is: 98 GB. I used bulk loading functions mentioned at http://virtuoso.openlinksw.com/d

Re: [Virtuoso-users] Segmentation Fault

Hi Hugh, Thanks Hugh! Currently, NumberOfBuffers is 120,000. My server has 3GB RAM. I will try to set NumberOfBuffers to between 2/3 and 3/5 of the RAM, and let you know if the server can be restarted. Erwin Leonardi On Tue, Feb 23, 2010 at 5:45 PM, Hugh Williams wrote: > Hi Erwin, > > In the

Re: [Virtuoso-users] Segmentation Fault

Hi Erwin, In the Virtuoso database directory what is the size of the virtuoso transaction log file (virtuoso.trx) as the server seems to have spent abt 15mins their rolling forward the pending transaction before running out of memory ? What is the "NumberOfBuffers" setting in your virtuoso.ini

[Virtuoso-users] Segmentation Fault

Hi, I start using Virtuoso Open Source for storing RDF data. This morning, the server was crashed while I deleted all triples from a particular graph. When I tried to restart the server, I got the following error message. 16:50:06 OpenLink Virtuoso Universal Server 16:50:06 Version 05.11.3039-pth

[Virtuoso-users] Segmentation fault

Hi, Just to keep you informed on release 6.0.0 with Ubuntu 9.10: we get also segmentation faults when installing packages. E.g. the logging when trying to install "Framework": root@ubuntu:~# cd /usr/local/virtuoso-opensource/var/lib/virtuoso/db root@ubuntu:/usr/local/virtuoso-opensource/var/lib/vi

Re: [Virtuoso-users] Segmentation fault in 5.0.7

Hi Erick, Can please provide: 1. An ODBC trace for an instance when the segmentation fault is occurring 2. An strace log from an instance when the segmentation fault is occurring 3. Is core file being created when the segmentation fault is occurring in which case we should be able to

[Virtuoso-users] Segmentation fault in 5.0.7

Hi Hugh, I' m using perl (DBI), unix odbc to load my graphs into our virtuoso instance. The process was executed successfully many times using v5.0.3. However, I got now (with 5.0.7) a segmentation fault and my perl script crashes, the virtuoso instance is still alive, and the graph seems to

Re: [Virtuoso-users] Segmentation fault

Eric, I've fixed this bug in the commercial version and the fix is now on its way to Virtuoso Open Source CVS. I guess that in few hours you'll get either updated version at SourceForge or a diff with 5.0.4 or both. The query you've provided returns empty result set for me, but it's due to inappr

Hi Erik, I have been able to create the seg fault running the query you provide below against a Mac OS X VOS 5.0.4 release build. This has been reported to development for analysis and resolution and we shall notify you when a fix is available. Best Regards, Hugh Williams Professional Services O

[Virtuoso-users] Segmentation fault

Hi, we're running 5.0.3 on a linux box. So far everything was going perfectly until we tested the following query which is very simple against a huge graph (that could be found here: http://www.cellcycleontology.org/ontology/rdf/cco.rdf): PREFIX rdfs:

Re: [Virtuoso-users] Segmentation Fault while RDF import

Hi Ivan , My machine is a intel core dual 2Ghz with 4GB RAM and one SATA disk under linux 64-bit. I had performance problems too (see other mail from yesterday). What i did is that i changed log to 0 before the import and back to 1 after. The problem was gone. It is only the import - no other acc

Re: [Virtuoso-users] Segmentation Fault while RDF import

Peter, Please try to make backup dump, as described in the doc; if it will report errors then crash-dump; then restore database from file. What's the platform and the compiler, BTW? Were there any queries executed or data manipulations in parallel with the import? Did you adjust numbers of buffers

Re: [Virtuoso-users] Segmentation Fault while RDF import

Hello Ivan, thank you. Good to know that you know the bug and fixed it. I changed the order and i also tryed to change ttlp_mt to ttlp. Always the same error. Sometimes sooner sometimes later. Is it possible to get a patch for Virtuoso 5.0.2 or is that to complicated? This would be very very nice

Re: [Virtuoso-users] Segmentation Fault while RDF import

Hello Peter, This bug resembles one that is fixed recently in commercial version of Virtuoso so next release of Virtuoso Open Source will probably contain the fix. The error is quite seldom (I've sen it only once on a dataset that is much greater than DBpedia) so you will probably not see it again
