Hi,
We have a number of automated tests which perform various operations on a
graph stored in TDB. When we were using using TDB 0.8.9, we had no memory
issue running the tests. We are now using 0.9.2 and we are getting
OutOfMemory errors while running the same tests and allocating the same
memory (see the stack trace below). Even if we double the heap space size,
we still see the errors. Is there something different we should be doing
with the updated version of the TDB library?
