Hi, I've been trying to think of a way to do this for a while and I'm stuck. I do coding in C but pretty new in Perl.

This is want I am trying to achieve :

I have a log file that contain log messages and separated by newline characters. Need to write a Perl program that finds the top 8 most reappeared log messages? Please note that the log file might be too big to fit in the memory at one time.

Think about that the log file has a format similar to Linux syslog format as follows: 

     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol unlock_
+page
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol generic
+_file_read
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol generic
+_file_write
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol generic
+_file_mmap
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol generic
+_file_sendfile
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: disagrees about versio
+n of symbol zone_table

+_fdatawrite
     Mar  9 08:15:05  gen-vcs11 kernel: kjslah: Unknown symbol find_or
+_create_page

so on... Any help would be greatly appreciated! Thanks!
