only 0 threading programs have output

Hello,

I ran successfully the program I-TASSER before, but suddenly when I am running it now I get the error: "only 0 threading programs have output, please check threading programs". I returned to jobs I ran successfully before, but I still get the error.
Example of an output:
Your setting for running I-TASSER is:
-pkgdir = /usr/local/I-TASSER4.1
-libdir = /usr/local/I-TASSER4.1
-java_home = /usr/
-seqname = Brix1
-datadir = /u/efratk/test/Brix1
-outdir = /u/efratk/test/Brix1
-runstyle = parallel
-homoflag = real
-idcut = 1
-ntemp = 20
-nmodel = 5
-light = true
-hours = 5
-LBS = false
-EC = false
-GO = false

1. make seq.txt and rmsinp
Your protein contains 353 residues:
