virtuoso core dumps

[qsecofr]

Hi,

I've just run into an issue where virtuoso dumps about 10 times per minute.

(virtuoso-t), uid 1000: exited on signal 10 (core dumped)

I'm not sure if nepomuk keeps spawning new virtuoso jobs, but they're both at the top of the job list seen via top.

I'm running FreeBSD8.2 release. KDE 4.7.3. And virtuoso-6.1.3_1.

I didn't see anything stand out in the log files in /var/log apart from the repetitive message above. Apparently no man page.

Logged in and su to root from Konsole:

#  /usr/local/etc/rc.d/virtuoso status
virtuoso is running as pid 3406.
# /usr/local/etc/rc.d/virtuoso stop
Stopping virtuoso.
kill: 3422: Operation not permitted

I do see the job in top runs under my user ID, but the directories & files are all owned by virtuoso:virtuoso in /usr/local/virtuoso
Possible permissions issue? Maybe something needs re-compile?

pkg_version -v

shows everything up to date except libpci, pciids.

Anyone else encountered similar?

Suggestions to turn off indexing might be a short term fix. But from the KDE menu the nepomuk controller will not launch.

And command line akonadi also fails.

UPDATE:
Found the following in ~/.kde4/share/apps/nepomuk/repository/main/data/virtuosobackend/soprano-virtuoso.log

Which corresponds to the date/time I began noticing problems. No idea what it really means. Maybe a new file I might've saved somewhere in my homedir path has "invalid" attributes?

SOLVED:
Seemingly. Not sure what the real underlying problem was. But I renamed the log, db, and temp-db files in the directory above. Seems things are back to normal.
