Hi, I installed ES 5.0.0-alpha 5 on Debian Jessie and cannot lock JVM Memory I set the below ``` echo 'elasticsearch soft memlock unlimited' | tee -a /etc/security/limits.conf echo 'elasticsearch hard memlock unlimited' | tee -a /etc/security/limits.conf /etc/elasticsearch/elasticsearch.yml bootstrap.memory_lock: true ``` on elasticsearch account ``` ulimit -H -l unlimited ``` in logs have this: ``` [2016-09-08 14:13:13,979][WARN][bootstrap] Unable to lock JVM Memory: error=12, reason=Cannot allocate memory [2016-09-08 14:13:13,980][WARN][bootstrap] This can result in part of the JVM being swapped out.

Hey, did you also configure systemd appropriately? See [https://www.elastic.co/guide/en/elasticsearch/reference/5.0/setup-configuration-memory.html#mlockall](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/setup-configuration-memory.html#mlockall) --Alex ---

Hi, I am facing a similar issue. Did you also set MAX\_LOCKED\_MEMORY in /etc/default/elasticsearch? ---
