Joshua McKenzie updated CASSANDRA-8152:
---------------------------------------
Resolution: Cannot Reproduce
Reproduced In: 2.1.2, 2.1.0 (was: 2.1.0, 2.1.2)
Status: Resolved (was: Awaiting Feedback)
Closing as cannot reproduce as it's been half a year since last update. If you
can get the information requested onto the ticket, we'd be happy to re-open and
look into this further.
> Cassandra crashes with Native memory allocation failure
> -------------------------------------------------------

> Key: CASSANDRA-8152
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8152
> Project: Cassandra
> Issue Type: Bug
> Environment: EC2 (i2.xlarge)
> Reporter: Babar Tareen
> Priority: Minor

> On a 6 node Cassandra (datastax-community-2.1) cluster running on EC2
> (i2.xlarge) instances, Jvm hosting the cassandra service randomly crashes
> with following error.
> {code}
> #
> # There is insufficient memory for the Java Runtime Environment to continue.
> # Native memory allocation (malloc) failed to allocate 12288 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=
> # This output file may be truncated or incomplete.
> #
> # Out of Memory Error (os_linux.cpp:2747), pid=26159, tid=140305605682944

> # Failed to write core dump. Core dumps have been disabled. To enable core
