Unable to run kafka on ec2 free tier instance

[Satendra Pratap Singh <sa...@gmail.com>]

Hi Team,

I have setup an one node kafka on ec2 free instance which has 8 gb ram and
256 GB hdd. I have installed java 8 on ec2. When I am trying to start kafka
getting error like

OpenJDK 64-Bit Server VM warning: INFO:
os::commit_memory(0x0000000700000000, 1073741824, 0) failed; error='Cannot
allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1073741824 bytes for
committing reserved memory.
# An error report file with more information is saved as:
# /home/ubuntu/kafka_2.12-2.7.0/hs_err_pid1920.log

I have increased the JAVA_HEAP but nothing happened. How to solve this
problem?

Looking forward to hearing from you.

Hi Satendra,

The JVM core indicates you are running out of system memory.
Increasing the heap size of your JVM will not help; if anything, it
will make things worse.
You need to check which processes occupy system memory (look for their
resident set size) and work on reducing memory consumption
accordingly.

Thanks,
Alexandre
