Andy
Thanks once again for your help and advice.
Yes, this question relates to the same data as my previous question. I had
already deleted the faulty DB and reverted to a clean backup copy, so can't
send you the nodes.dat file, but if it happens again, I'll keep a copy.
The problems have occurred when I have been loading the same .ttl file. I'll
email you a copy of that in case it helps. I think everything in it is ASCII,
but not impossible that somewhere in it there is 2-or-more char Unicode.
tdbrecovery sounds useful - I had assumed that stopping fuseki (via
/etc/init.d) would 'clear up' but sounds like not necessarily. Can't see any
docs on tdbrecovery. How should i use that? With a --loc={path to tdb dir} ?
Will set up some newer versions. Since my first and second posts to the list,
I upgraded to:
fuseki:
Jena: VERSION: 2.7.0-incubating
Jena: BUILD_DATE: 2011-12-14T14:54:09+0000
ARQ: VERSION: 2.9.0-incubating
ARQ: BUILD_DATE: 2011-12-14T15:04:27+0000
TDB: VERSION: 0.9.0-incubating
TDB: BUILD_DATE: 2012-02-29T19:39:52+0000
Fuseki: VERSION: 0.2.1-incubating
Fuseki: BUILD_DATE: 2012-03-16T15:08:53+0000
and tdbloader:
Jena: VERSION: 2.7.0-incubating
Jena: BUILD_DATE: 2011-12-14T14:54:09+0000
ARQ: VERSION: 2.9.0-incubating
ARQ: BUILD_DATE: 2011-12-14T15:04:27+0000
TDB: VERSION: 0.9.0-incubating
TDB: BUILD_DATE: 2012-02-29T19:39:52+0000
Thanks
