Heap space needs to be cleared


#1

getting out-of-memory errors on the cluster

There is insufficient memory for the Java Runtime Environment to continue.

Native memory allocation (mmap) failed to map 350748672 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=
