Running fine, but suddenly met with org.apache.commons.math.MathRuntimeException$4: standard deviation must be positive (0)

Have not found anyone encountering this problem and was wondering if anyone would have any idea. The run was set for 500,000,000 chains but was met with the following error after 387,000,000 runs

Hi, 

I am running into the exact same issue. Were you able to figure it out?

Thanks,

Same here, after 83,757,000 samples. Did you find any explanation for the error?
