in the root crontab, about the follozing entries (currently commented out by me): #CZ30 0 * * * /root/check.tables #CZ22 23 * * * du -cs /* > du_slash_`date -I` #CZ23 22 * * * du -cs /home/aras/backup/* > du_home_aras_backup_`date -I` #CZ27 22 * * * du -cs /home/aras/acis/* > du_home_aras_acis_`date -I` #CZ33 22 * * * du -cs /home/* > du_slash_home_`date -I` #CZ36 01 * * * du -cs /var/lib/mysql/* > du_var_lib_mysql_`date -I` #CZ39 01 * * * du -cs /var/* > du_slash_var_`date -I` Are they any good? The machine crashed twice after du -cs /* > du_slash_`date -I`, as far I can see, and I just tried du -cs /home/* > du_slash_home_`date -I` which took several minutes with full load, and the machine was not responsive for a while after that. This worries me. Christian Zimmermann FIGUGEGL!
