Description (partial)

Symptom:
The /var/tmp directory is full because the npacl.debug file is using up all available space.

Once the directory is full, many commands will not complete if they require space in this directory. For example show tech-support and ISSU may not complete while the /var/tmp directory is full.

As the /var/tmp directory is filling, messages similar to the following will be seen on the switch:
1970 Jan 1 00:00:00 switch %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 97%.
1970 Jan 1 00:00:00 switch  %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 98%.
1970 Jan 1 00:00:00 switch  last message repeated 1 time
1970 Jan 1 00:00:00 switch  %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 99%.
1970 Jan 1 00:00:00 switch  last message repeated 1 time
1970 Jan 1 00:00:00 switch  %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 100%.
