[molpro-user] Test error on AIX 5.2L for parallel runs

[Sigismondo Boschi]

Hi,

This error should be related to the fact that asyncronous I/O (AIO) is 
not enabled on your machine: contact the system administrator to enable 
it and try to run again. I know of a similar error for the NWchem 
package, and it seems to be the same.

Regards,

    Sigismondo
