OrientDB Update runs into JVM memory issue 'Cannot allocate memory' - jvm

Question

I just updated my OrientDB to the latest Version. So I just took the complete folder to test it without my custom settings. Then I tried to start the new version with:
sh server.sh
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e04a0000, 357957632, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 357957632 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /home/ubuntu/orientdb/bin/hs_err_pid1885.log
But as you can see there is trouble with the JVM. Something with memory. But I did not change any setting. So how can this come?
I also cannot rember to set some custom Java settings on my system. Is there a way to check it?
What I changed
<properties>
<!-- DATABASE POOL: size min/max -->
<entry name="db.pool.min" value="1"/>
<entry name="db.pool.max" value="50"/>
<!-- PROFILER: configures the profiler as <seconds-for-snapshot>,<archive-snapshot-size>,<summary-size> -->
<entry name="profiler.enabled" value="true"/>
<!-- <entry name="profiler.config" value="30,10,10" /> -->
<!-- LOG: enable/Disable logging. Levels are: finer, fine, finest, info,
warning -->
<entry name="log.console.level" value="info"/>
<entry name="log.file.level" value="fine"/>
<!-- Memory -->
<entry name="memory.chunk.size" value="‭20971520‬"/>
</properties>

You should change one line in sever.sh from ORIENTDB_OPTS_MEMORY="-Xms512m -Xmx512m" to ORIENTDB_OPTS_MEMORY="-Xms128m -Xmx256m"
