Sounds like you are seeing backend crashes. Does the postmaster log
show any complaints about unexpected child process exits? Are there
any core files laying about in the database subdirectories? Ideally
I'd like to see a debugger backtrace from a core file ...
In any case, this is not a Java or JDBC problem, it's a backend problem.
