The default of 512 may be too low in certain situations leading to vfork()
failing with errno=EAGAIN when trying to spawn lock-helper processes.
With the default for LockProcessesPerDB being 200 the increased TasksMax limit
should cover the problematic scenario.
Additional background: the failing vfork()s have been seen on production
clusters and were tracked down to being logged in the context of ctdb calling
tdb_repack().
