Have you use IPCS with the LE VERBX function? LE normally will have a handle routine that will capture the true abend and stuff it into storage before it allows the dump processing to continue. I am not sure if this particular event will do that, but it might.
Otherwise I would open an SR To LE support and have them assist in debugging this. It might be something they have not handled before.
