> I have also same issue, after check in dmesg…identified low memory Error,is any solution use precompiled one [4464.550217] Out of memory: Kill process 2708 (julia) score 386 or sacrifice child [4464.555547] Killed process 3014 (julia) total-vm:727572kB, anon-rss:167824kB, file-rss: 676kB, shmem-rss:0kB

Someone just posted here. The post was basically experiencing the same “failed to map segment from shared object” for sys.so during precompilation. Basically they had a lack of memory. When I did my virtualbox test it was with 4gb in the VM.

I was able to reproduce your problem when I dropped the RAM down to 1GB with 1GB of swap space…so my guess would be you need more memory. 🙂
