Has anyone faced the same problem? Thank you very much in advance.

Answer 1

I was able to solve this problem by adding a swap file to the system (there was had no swap at all).

For more details about the reason of that problem look here .

This is the key fragment:

In that case the problem was the linux kernel running out of virtual memory. The kernel OOM (out of memory) killer then stepped in and killed the most (un)deserving victim/runaway process which happened to be the GWT/maven build process.

To determine if that is the case you can use the {{dmesg}} command from a linux shell. Somewhere towards the end of the output there will be a line similar to

{code} Out of memory: kill process 946 (daemon) score 1073527 or a child {code}

For reference the status code 137 (128 + 9) typically means (can differ between flavours of unix). That the process was terminated by receipt of a signal. In this case signal 9 which is SIGKILL and unblockable kill.

If this is the case the underlying machine/OS needs more virtual memory. This can be added by either adding physical memory or swap space as appropriate.
