Jenkins / JENKINS-61045 Native memory allocation (mmap) failed to map 12288 bytes

Change By: nicola limongi

I'm experiencing recurring Jenkins crashes due to memory allocations problems. I'm looking at the JVM Hotspot error file retrieved via Jenkins's Monitoring page, but I can't understand why the JVM crashed if the available memory was still MemAvailable: 3802204 kB. Can you please help me to understand what's wrong?
