The following could help you to increase more space in /tmp.
You need to make alternation in the file /scripts/securetmp
Find the entry my $tmpdsksize under Global Variables as follows:
# Global Variables
my $tmpdsksize = 512000; # Must be larger than 250000
Change the value for that particular entry to desired size.
Then make sure that no processes are using /tmp using the command, lsof /tmp
Please stop the service /etc/init.d/mysql stop. Also delete the file, /usr/tmpDSK if it exists by rm -rf /usr/tmpDSK
Run the script
Then you will asked for some confirmation steps.
“Would you like to secure /tmp at boot time?” Press y
“Would you like to secure /tmp now?” Press y
Eventually you can see the upgraded space to /tmp in server 🙂
