cron error: /var/tmp/.../t ???

i'm noticing some cron errors sent to (admin/root email) and am wondering what this is "/var/tmp/.../t"
error message in the email says:
"Subject: Cron <nobody@cpanel1> /var/tmp/.../t"
body: bind: Address already in use
Edit: cron email now reports: /bin/sh: /var/tmp/.../t: Permission denied End edit

Can someone a) tell me what this is b) tell me what i need to do to fix it?

Code:

root@cpanel1 [/var/tmp/...]# ls -l
total 1468
