HDFS, Failed to start namenode, java.lang.OutOfMemoryError, unable to create new native thread

I've installed CDH-5.16.1-1.cdh5.16.1.p0.3 on SLES 12.3 in "single user mode".

I have some services running

• cloucera-scm-server
• cloudera-scm-agent
• Cloudera Management Service (Alert Publisher, Event Server, Host Monitor, Service Monitor)
• Zookeeper

When I try to start HDFS, Secondary Name Node and Data Node seems ok, but Name Node fails with this error:

2019-01-25 17:21:52,016 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode.

I immediately thought it was ulimits related issues, so I modified it.

cloudera-scm soft nofile 32768
cloudera-scm hard nofile 1048576
cloudera-scm soft nproc 127812
cloudera-scm hard nproc unlimited
cloudera-scm soft memlock unlimited
cloudera-scm hard memlock unlimited

Nothing changed.

Someone suggested me to change servicemd related limits, we raised service-related limits and last run has very high value, but Name Node continues to fail

> ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited

I also raised Name Node log level to trace, but logs are pretty clean

Any suggestion?
