pwd: couldn't find directory entry in `..' with matching i-node (Standalone I-TASSER v1.1)

Dear Sirs,

Encountered some output messages during the simulations stage in I_TASSER. Would appreciate comments about this. Full console out is in the attached txt file.

3.2 make restraints
4.1 run simulation
run 20 serial simulations
run simulation job 1 / 20
run simulation job 2 / 20
run simulation job 3 / 20
pwd: couldn't find directory entry in `..' with matching i-node
run simulation job 4 / 20
pwd: couldn't find directory entry in `..' with matching i-node
run simulation job 5 / 20
pwd: couldn't find directory entry in `..' with matching i-node

I noticed that output msg happens only when running two instances where seq.fasta are in different datadir but using the same seq name in commandline argument. Read a thread about bad placement of "$unicode" in runI-TASSER.pl.
Would changeing sequence name in command line argument to run I-TASSER allow running more than one instance?

Best regards,

James
