Low global exclusion count errors

Dear NAMD users,
I ran into the "Low global exclusion count errors" after about 20 ns of production dynamics.

1). I increased the pairlist distance and set "COMmotion no" after the first instance, but still encountered the same error around ~20-23 ns. Temperature, potential and kinetic energies are all stable throughout.

2). After reading the section on "Bad global exclusion count errors" on this link: http://www.ks.uiuc.edu/Research/namd/wiki/index.cgi?NamdTroubleshooting

I included the "splitPatch position" option set "rigidbonds none" and "COMmotion no." Now the temperature is no longer maintained at 310K.

Any suggestions will be appreciated.
