libdbcsr, MPI error

[nadler]

The error still comes up after several intents. Current version
installed is 2.2.45. Furthermore, as mentioned in the first post:
independently of the number of cpus chosen, the execution stops after
a certain amount of cpu hours. In my case it is around 100 +/-10
hours; the guy from the support team told me that the same happens to
him after 163 +/-2 cpu hours, using the same input file I am using.
Any ideas about what could be the problem? Following, I put
informations about the clusters, compiler and current archfile.
Thanks!

Compiler: IBM XL Fortran for Linux, V12.1

The information about the machines:
Once, 1036 nodes of eServer BladeCenter JS20, having 2 PPC cpus
(2.2GHz) with 4GB RAM per node.
Then, 168 nodes of eServer BladeCenter JS21, having 4 PPC cpus
(2.3GHz) with 8GB RAM.
Communication occurs via Myrinet.

The current archfile is:
