Hi all

Recently I have a problem that for some unknown reason, maybe I terminated parallel calculation abruptly, LaunchKernels fails and shows the following messages:

In[1]:= LaunchKernels[]

ReplaceAll::reps: {Null, Version -> 3.01, CVSRevision -> 1.36, LocalStatus -> Hold[{<<4>>}, <<4>>, {<<4>>}], <<15>>, ParallelPalettepaletteConfig[Local Kernels, Batch] -> {}, debugPreference[Batch] -> False} is neither a list of replacement rules nor a valid dispatch table, and so cannot be used for replacing.

ReplaceAll::reps: {Null, Version -> 3.01, CVSRevision -> 1.36, LocalStatus -> Hold[{tr[LocalPro<<16>>elName], <<3>>}, <<5>>], <<15>>, paletteConfig[Local Kernels, Batch] -> {}, debugPreference[Batch] -> False} is neither a list of replacement rules nor a valid dispatch table, and so cannot be used for replacing.

Throw::nocatch: Uncaught Throw[ParallelPreferencesPrivate`nopref[Version], Preferences] returned to top level.

Out[1]= Hold[Throw[ParallelPreferencesPrivate`nopref[Version], Preferences]]

How to fixed this problem under Linux? The Mathematica version is 9.0
