Hi,

 I just Googled the erro message :
VMI/GM: send completed with send error 0x00000012
 here it is what it says:

What does VMI/GM: send completed with send error 0x00000012 mean?

      VMI/GM: send completed with send error 0x00000012 means there is a
problem with the Myrinet network on one or more nodes. If this error
occurs, please send email to consult_at_ncsa.uiuc.edu and send the standard
error and output files from the batch job that failed.

so you should sent email to consult_at_ncsa.uiuc.edu and report this error.
