  • Try running with the -X Maven flag to turn debug output on, that might give you/us some more troubleshooting angles. – Jason482 Jul 21 '11 at 20:24

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.

    +1, the notes on dmesg helped me figure out an issue with a JVM task, under Hadoop, getting killed without any specific reason. Also, learned a bit more about the status code numbers' relevance :). Thanks – Kiran Subbaraman Dec 10 '12 at 17:48

    I don't think that the Xmx option helps, since then the JVM would notice the lack of memory and exit with a different error. When the kernel kills a process there must be a real lack of memory. – Tarion Apr 28 '15 at 07:55
  • Indeed with `dmesg` you can see the exact reason that your process has been killed (by sending it a signal) by the OS! Just run it after your crash, and you will see the exact reason with some additional detail as long as you knew your process id. – matanster Apr 18 '20 at 07:25

For me, I found that the problem was too much memory being allocated, not too little.

When running the job on a machine with 2GB of memory and setting the max heap size to 2GB, the build eventually failed with status 137. However when setting the job to 1GB maximum (e.g. -Xmx1g -Xms512m), the build succeeded.

This kind of makes sense, because the JVM will freely increase its memory up to the maximum heap size, but if there's not enough real memory, the OS will kill the process. However, if you reduce the max heap size, the JVM won't try to increase its memory so highly, so the OS won't worry about it enough to kill it.

Furthermore, I was using GWT which forks a separate process for compilation, and the arguments have to be specified as an extraJvmArgs element within gwt-maven-plugin configuration, not in MAVEN_OPTS.

I had this problem and my system admin found a number of hung processes on the Bamboo server. Clearing those processes resolved the issue. It may not be anything directly to do with your own build.

Try another version (or a fresh installation) of JDK/JRE. It looks like java executable is crashing while running GWT compiler. You can also try to compile it another machine to confirm that the problem is with the JDK/JRE installation.
