this sounds like you have one of two possible problems here:

- your executable uses different versions of OpenMPI on different nodes.
  thus the correlation between the error and ultrasoft psps is coincidence

- you run into a situation where communication is overlapping in
unexpected ways and thus messages are received where others were
expected. this could be due to a bug in the code, but it could also be
due to having a version skew between executables used on different
nodes (where there is a difference in communication patterns between
versions for ultrasofts, but not for normconserving).
