--------------------------------------
Summary: High memory usage / memory leaks in ZeppelinServer and
RemoteInterpreterServer processes
Key: ZEPPELIN-1685
URL: https://issues.apache.org/jira/browse/ZEPPELIN-1685
Project: Zeppelin
Issue Type: Bug
Reporter: Prasad Wagle
After a week of operation we have seen high memory usage for the ZeppelinServer
and RemoteInterpreterServer processes.
ZeppelinServer: VSZ: 6.6 GB RSS: 4.3 GB
RemoteInterpreterServer for md: VSZ: 6.3 GB RSS: 2.6 GB
VSZ = virtual memory usage of entire process (in KiB)
RSS = resident set size, the non-swapped physical memory that a task has used
(in KiB)
If this continues, the jvm crashes with error:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 877658112 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
The workaround is to restart the processes periodically.
