Memory problem: 'error=12, Not enough space'

Issue

You see this stack trace in build logs:

Caused by: java.io.IOException: error=12, Not enough space
    at java.lang.UNIXProcess.forkAndExec(Native Method)
    at java.lang.UNIXProcess.<init>(UNIXProcess.java:79)
    at java.lang.ProcessImpl.start(ProcessImpl.java:130)
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1023)▼

Environment

Resolution

You are running out of system memory on agent node when Java calls fork(). This situation can be triggered when agent (agent.jar JVM process) uses too much memory.

If command line launch argument of agent doesn’t contain any memory limiting parameters, you should add them, for example:

-Xms512m -Xmx512m▼
