	For the third time within the recent past, a GIANNI task - this time: gpcrmd_4mqt_complex_noNA_rep_3-GIANNI_CPXB-0-10-RND4540_0 failed after a few seconds. stderr says: ERROR: file mapmdx.cpp line 812: VDW table too large Others were completed o.k. Anyone else making same experience? What is "VDW table"?

	Another "... complex ... GIANNI..." task that failed, this time though after about 32.000 seconds: gpcrmd_4oo9_complex_noNA_rep_3-GIANNI_CPXB-6-10-RND5783_5 stderr says: # Simulation unstable. Flag 3 value 1 # The simulation has become unstable. Terminating to avoid lock-up # The simulation has become unstable. Terminating to avoid lock-up (2) # Attempting restart (step 6965000) called boinc_finish :-(

	What is "VDW table"? VDW probably means Van der Waals. https://en.wikipedia.org/wiki/Van_der_Waals_force # Simulation unstable. Flag 3 value 1 # The simulation has become unstable. Terminating to avoid lock-up # The simulation has become unstable. Terminating to avoid lock-up (2) # Attempting restart (step 6965000) One possibility is you may need to clock back your GPU a bit.

This workunit has failed on every host (including one of mine) with the same error message. It is very unlikely that 8 different GPUs (including known reliable ones) have the same condition which makes the workunit fail the same way. In this case the source of the error is the algorithm which checks the stability of the simulation probably set to an overly sensitive level.
