The workstation has Linux system. I am using a recent updated julia-0.4.5. I downloaded the binary version and set up path to bin file to call Julia.  It is fine to do  julia abc-jl  However, when I did following,  julia -p 16 abc-jl  Error: Could not allocate pools  Then I type,  ulimit -a   linan pd-srv-msa-01   $ ulimit -a core file size           blocks, -c  0 data seg size            kbytes, -d  unlimited scheduling priority              -e  0 file size                blocks, -f  unlimited pending signals                  -i  1390380 max locked memory        kbytes, -l  64 max memory size          kbytes, -m  unlimited open files                       -n  1024 pipe size             512 bytes, -p  8 POSIX message queues      bytes, -q  819200 real-time priority               -r  0 stack size               kbytes, -s  10240 cpu time                seconds, -t  unlimited max user processes               -u  1024 virtual memory           kbytes, -v  unlimited file locks                       -x  unlimited  Could you please let me know where this problem come from and how to solve this problem?  Thanks very much.  Linan     Mauro    Oct 13   I think this is https:  github.com JuliaLang julia issues 10390
