I've had better experience with using EEM instead of Kron. If you just
need the filename to semi-unique you could use the uptime:

! Define an RMON event to react only when the CPU is busy
rmon event 10 log description "1 minute avg. CPU > 90%"
rmon event 11 log description "1 minute avg. CPU < 70%"
rmon alarm 10 lsystem.57.0 5 absolute rising-threshold 90 10 falling-threshold 70 11
!
! If using TACACS+ and command authentication you need to specify a username
event manager session cli username "<tacacs-needs-a-username>"
!
event manager applet EEM-copy-mem-usage
 event timer cron cron-entry "0 */2 * * *" 
 action 1.0 info type routername
 action 1.1 info type snmp oid 1.3.6.1.2.1.1.3.0 get-type exact
 action 2.0 cli command "enable"
 action 2.1 cli command "show processes memory sorted | redirect tftp://192.0.2.10/$_info_routername-$_info_snmp_value-mem-usage.txt"
 action 3.0 syslog msg "Memory usage copied to tftp://192.0.2.10/$_info_routername-$_info_snmp_value-mem-usage.txt"
!

(By the way: Your subject is waaay too long for comfort. Subjects should
not contain information in themselves. :-))
