Dear Experts,

One of my recon-all seems to be in a hung state. Started the recon at 10AM and its still going on – we have other brains that typically finish within 4 hrs.

These are the last few entries from the recon-all log. Should I kill this process? What could be the root cause for this state?

Any help appreciated. TIA!
