The lock files seem to be in /tmp/Harris/License/ and following the naming convention of .cllsem_FCU[8 digits].lock .cllsem_FLT_[8 digits].lock .cllsem_shmFCU[8 digits].lock Took out the 8 digit number in case it's license related. In particular, when running 'strace idl', idl hangs on the '_FCU' dot file: ... open("/tmp/Harris/License/.cllsem_FCU[8 digits].lock", O_WRONLY\|O_CREAT\|O_TRUNC, 0666) = 7 fcntl(6, F_SETLKW, {l_type=F_WRLCK, l_whence=SEEK_CUR, l_start=0, l_len=0} ... This is a RHEL7 system with SELinux enabled.

When you say ENVI and IDL hang on the system, what specifically do you see occurring with your usage? Are multiple users attempting access at once?

Apologies for the late reply. Yes, user1 is running idl and another user tries to start a session, but it hangs. When doing a 'strace idl', the command hangs on trying to open/create a lock file in the /tmp/Harris/... path. Running into this again today. My temp solution is to delete the /tmp/Harris/License directory.
