I am using the version tdb 0.9.4 and jena 2.7.4 and also I use
transactions in my code.
Could you show more of your code?
Is the ontmodel_ obtained inside a transaction?
The corruption to the node table most likely happened in the past - it's
the read operation detecting the problem, not causing it.

Hello, everyone,
Which version are you running?
when I call the following method:
ontmodel_.write(new FileOutputStream(new File(path+filename)));
I have got an error as following several times, if anyone can tell me
what is the possible reason for this? thank you very much.
The node table is corrupt. This is usually caused by not closing the
database down cleanly when used non-transactionally. In old versions, some
concurrency problems could also cause thsi as well, but this is now presumed
fixed.
