I am utilizing PyFoam to run a number of OpenFOAM cases wherein the value of the velocity on a boundary is parametrically varied. PyFoam works well but I continue to get the following error sporadically:

Getting LinuxMem: [Errno 2] No such file or directory: '/proc/19787/status'

I have isolated the error to the following lines in my python run script:

run=BasicRunner(argv=[solver,"-case",case],silent=True,noLog=True)
run.start()

The solver is simpleFoam and case is the name of the case directory.
OpenFOAM version 2.3.0.
PyFoam version 0.6.5
Ubuntu 12.04.05

The script still runs just fine and produces the desired output, but I would like to eliminate this error. Any help would be much appreciated.

That just means that the solver ended very quickly. PyFoam looks at the file /proc/<pid>/status to find out how much memory the process with the process ID <pid> uses. If the process ends before PyFoam can have a first look at the file the file is gone and you get the above error message. Nothing harmful happens. Any solution for this cosmetic problem: don't bother your computer with tiny cases

Thanks Bernhard. I thought it had to do with the speed with which the cases were running as inserting a few time.sleep() remedied the situation. I will keep this in mind when running small cases for debugging purposes.
