ASI Mismatch error

Arnab

I've been running a moving mesh with ASI in which I run one revolution with each run. I've been increasing the pressure under-relaxation with each restart (I restart with the new BC type option even though I'm not changing BC type). For my last run I increased the pressure under-relaxation from 0.5 to 1.0 and I decreased the U,V,W,T residual tolerances for 0.01 to 0.0001. It ran 3/4 of a revolution and then stopped with the following message: **** ERROR #240 **** 1 MASTER FACES AND 1 SLAVE FACES REMAIN UNMATCHED CHECK MOVING GRID COMMANDS, OR CHANGE AREA TOLERANCE FACTOR (RCON 12) CURRENT TOLERANCE FACTOR: 0.200000E-01 CHANGE TO AT LEAST 0.50588

The ASI area mismatch error occurs no matter what solver parameters we use.

Please let me know the possible causes for why we can run 3 revolutions fine, but on the 4th one the error occurs.
