RSA NetWitness Logs & Network: FNESERVER service won't start

Issue

Customer is getting a lockfile error when trying to stop or start fneserver service and so he's not able to connect to licensing server and getting red annoy banner.
Customer tried going through steps from https://community.rsa.com/docs/DOC-47054, but that didn't fix the issue.

Errors observed:
lock file found but no process running for pid 30086 
PosixMutexImpl::PosixMutexImpl: Could not verify lockfile directory access rights: Invalid argument

Tasks

Check the permission of the /tmp directory.
The fneserver is writing files to this directory.
It should have correct permission which is drwxrwxrwt

Resolution

Review the /tmp directory permission and make sure it is set to drwxrwxrwt
If it is not set correctly then you can perform the following command:
#chmod 1777 /tmp
