Just in case other people hit these problems and don't check the bug tracker - I believe I've found and fixed (at least for my config) a couple of problems in 2.5.1p1
1582254 - under some conditions skipping a DLE (because of "strategy skip" in the dumptype definition) can cause the in-code list of DLEs to be corrupted.
1586596 - delayed start of dumps with starttime doesn't work because the value stored from the config file definition isn't what the driver code expects.
I've supplied patches for both of these problems - they fixed them for me but would probably benefit from a look over from someone who knows the code better.
