SAP Note #22099 : parameter to fix the issue

The space available in the C table tm_adm is not sufficient for another
terminal to log on to this applicatin server. The number of table
elements is determined by the profile parameter 'rdisp/tm_max_no'
when the application server is started.
Important: For internal purposes one entry for each work process and
one entry for each CPIC connection is made in tm_adm in addition to
an entry for each work process.

Analysis:
- recheck the profile parameter, file of instance parameter, also try run RSPARAM report, check in all instance one by one
- check SNAP table or SM21
- memory utilization , check in SM50 especially when status PRIV found or NRIV (?)

- session number, computer terminal / workstation number

- a transaction also can open a new other session

- check netstat -a for connection number
