> # Native memory allocation (mmap) failed to map 7158628352 bytes for
> committing reserved memory.
> # Possible reasons:
> # The system is out of physical RAM or swap space
> # In 32 bit mode, the process size limit was hit
> # Possible solutions:
> # Reduce memory load on the system
> # Increase physical memory or swap space
> # Check if swap backing store is full
> # Use 64 bit Java on a 64 bit OS
> # Decrease Java heap size (-Xmx/-Xms)
> # Decrease number of Java threads
> # Decrease Java thread stack sizes (-Xss)
> # Set larger code cache with -XX:ReservedCodeCacheSize=
> # This output file may be truncated or incomplete.
