[CP2K-user] how could the RAM for ADMM be negative number

[Sun Geng]

Dear CP2K users, 
I am running jobs with CP2K/ADMM method, in which the CP2k prints the 
following lines:

  HFX_MEM_INFO| Number of cart. primitive ERI's calculated:      
 52451602395221
  HFX_MEM_INFO| Number of sph. ERI's calculated:                  
 2343013195064
  HFX_MEM_INFO| Number of sph. ERI's stored in-core:              
 2247108266900
  HFX_MEM_INFO| Number of sph. ERI's stored on disk:

  HFX_MEM_INFO| Number of sph. ERI's calculated on the fly:

  33
  HFX_MEM_INFO| Est. max. program size after HFX  [MiB]:                  
 31121

The total memory consumption ERI's RAM is a negative number.
Why it is a negative number? 
How can I know the real RAM consumption in this job?
Thank you very much in advance.
Best
Geng
