error: SQL30081N A communication error has been detected

If you receive an error: SQL30081N A communication error has been detected at unix enviromnet, simply attach to the instance and run the command db2start to review if all processes started correctly (e.g. db2wdog)
If not, check date of last modification the file /etc/services.
When the date of modification is older then the error occured, try check db2set settingsi if DB2COMM = TCPIP
