Log Parser and Log Collector process's fail to start.
It is a common procedure to increase the security on operating systems. For Linux based systems adding noexec flag to the /tmp is part of this security hardening. Log Parser and Log Collector are logstash process's and there is a known issue with logstash version and a noexec /tmp.

After that we can just restart logparser/logcollector with below commands: ./$CA_EMM_HOME/bin/startServices.sh –LP –LC
