What changes would you recommend in /etc/syslog.conf (quoted last below)?

# ls -ltr user.log syslog messages
-rw------- 1 root root 47853952 Sep  4 09:39 user.log
-rw------- 1 root root 47943929 Sep  4 10:28 syslog
-rw------- 1 root root 47949714 Sep  4 10:28 messages

These seem to be essentially redundant. Is it safe to eliminate some? and
which?

Although the greater question is why is are so many errors being posted?

-rw------- 1 root root      36384 Aug 12 03:53 user.log.4.gz
-rw------- 1 root root      39396 Aug 19 03:58 user.log.3.gz
-rw------- 1 root root      47818 Aug 25 14:40 user.log.2.gz
-rw------- 1 root root 2147483647 Aug 31 09:26 user.log.1
-rw------- 1 root root   47853952 Sep  4 09:39 user.log
