pardiso_handle_store hangs

Hi,

I'm using pardiso for a project at work.  Everything seems to be working well except when attempting to store the handle after performing matrix factorization.  For some reason, pardiso_handle_store seems to be hanging at some point during the file write.  It writes a portion of the file, but never seems to complete.  I've left the process running for days, but the file size doesn't grow beyond a certain point, and the "last modified" timestamp indicates that it hasn't been touched in days.

We are using the ILP64 version of MKL, and we've tried both the sequential and parallel implementation of the package.

Are there any suggestions on things that we can try?

Thanks!
