Error "epsilon too small" when using DPM

[Sacaq]

Hi~

I am using ANSYS14 to simulate drop particle in a cylinder by DPM(Discrete Phase Model) and LES model(Large-Eddy-Simulation model).
The error "epsilon too small" appeared after 1.82 seconds, that is Flow time = 0.183s, time step = 183, which is as follows:

Can anyone kindly help?
Thank you!

It seem solved after I re-startup the computer.

In a while, I encountered an Error 10054 that said that the case can't run in a parallel way.

"
...Internal Error: ReadProcessMemory() failed MPI Application rank 2 exited before MPI_Finalize() with status 1 999999
(..\src\mpsystem.c@1173): mpt_read: failed: errno = 10054 999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory
"

It's solved after re-plugging the memory modules and re-read the license file.
