The system sometimes reports errors like the following: WARNING: / tmp: File system full, swap space limit exceeded there are several common reasons for this error: 1) insufficient physical memory; 2) insufficient Swap space; 3) some users are using the / tmp file system; 4) specific programs take up a lot of memory; 5) some error scripts run out of resources indefinitely. For the errors caused by the above reasons, the following measures can be taken: 1) increase the physical memory. 2) add Swap-the following method can be easily implemented (Note: the added Swap will disappear as the system restarts) # mkfile [g | k | b | m] / swap # swap-a / swap-run "swap-l" to confirm the appended Swap. 3) inform the user of matters needing attention when using / tmp. 4) Kill program. 5) modify the script. Find the reason for the error:-use the command to find out which program takes up the most resources or whether there are scripts that infinitely deplete resources. # / usr/bin/ps-el | sort-rn-k 10 cases: how to calculate the resource size > bash-2.05# / usr/bin/ps-el | sort-rn-k 10
