Can you check if these 2 processes are still around using 'ps -p 2398610 2398617'?
It looks like your recon-all is started with '-parallel' option. It is the multi-processing done at the recon-all level. There is no synchronization mechanism to ensure shared resources access/update. Use '-nthreads N' to enable multithreading at each program level.

External Email - Use Caution 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!
