@shan1

is there any detail of Neo4j version? Is this Neo4j v5? or 4.4? or ?

Also regarding

4423624627613877252.so: /tmp/libzstd-jni-1.5.0-4423624627613877252.so: failed to map segment from shared object
no zstd-jni-1.5.0-4 in java.library.path: [/usr/java/packages/lib, /usr/lib/x86_64-linux-gnu/jni, /lib/x86_64-linux-gnu, /usr/lib/x86_64-linux-gnu, /usr/lib/jni, /lib, /usr/lib]

this is because your /tmp is defined with noexec
Per https://neo4j.com/docs/operations-manual/5/configuration/file-locations/#file-locations-permissions which is a link to the Neo4j v5 doc but the following snippet is also applicable for v4.4.x etc

If tmp is set to noexec, it is recommended to set dbms.jvm.additional=-Djava.io.tmpdir=/home/neo4j in conf/neo4j.conf. Additionally, replace /home/neo4j with a path that has exec permissions.

For /bin/cypher-shell, set this via an environment variable: export JAVA_OPTS=-Djava.io.tmpdir=/home/neo4j and replace /home/neo4j with a path that has exec permissions.
