And in crontab i had these entries.

prerouter-07: prerouter# crontab -l
#ident "@(#)root 1.21 04/03/23 SMI"
0 * * * * /usr/local/sbin/mkhomedir >/dev/null 2>&1

#
# The root crontab should be used to perform accounting data collection.
#
#
10 3 * * * /usr/sbin/logadm
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean

Search for and read /etc/logadm.conf?

or simply jboss (or whatever creates these prerouter logs) configuration. It might just rotates/archives its own logs.
