-------------------------------------
Summary: out of memory error on very long running tablet server
Key: ACCUMULO-1770
URL: https://issues.apache.org/jira/browse/ACCUMULO-1770
Project: Accumulo
Issue Type: Bug
Components: tserver
Reporter: Eric Newton
Assignee: Eric Newton
On a large cluster it was noticed that a few of the tablet servers had been
pushed into swap. This didn't effect the performance of the server until it
ran out of memory, and the process was killed. The gc reports in the debug log
showed the system had plenty of heap space for the JVM. The number of threads
in the server where not excessive (dozens). This cluster ingests some large
values (megabytes). The tablet server had been up for a month prior to running
out of memory. MALLOC_ARENA_MAX had already been set to 1.
* Investigate the effect of fragmentation on memory usage for large value
inserts.
