I noted the /tmp file system full, swap space limit exceeded through the OS
dmsg log. Need help to clarify the following :

1) What does this message means ? Is this message critical ?

2) If a program/job/process encounter the error, the program/job/process
will not be completed/abandoned or it will wait until has enough space on
/tmp and then continue ?

3) What can be done to resolve it and prevent it from happening ?

Thank youy very much for your help.
