@trquinn reported the following:

I'm getting the following abort using the CkIO on a Lustre file system.

This is for charm version Converse/Charm++ Commit ID: v6.9.0-300-g99cda7a11

Any ideas to fix this?

I wasn't able to reproduce this on Stampede 2 (my Blue Waters account is currently inaccessible), so I haven't tested and verified that the fix in #2457 actually works, but I'm pretty sure it will.
