The question "So these errors happen while the file is being rebuilt, right?" is a very good question but it is difficult for me to answer with certainty. One of our email gateways collects data and builds the input file every hour per a cronjob: root@mg06:/var/local/vaproc/bin# crontab -l | grep bld_aliases 35 * * * * /var/local/vaproc/bin/bld_aliases.sh After that cronjob has run each gateway has a new copy of the virtualaliases file and each executes a postmap and a reload. I collected the log lines from all the gateways and counted the number of events in each minute of every hour of all the days. In that process I did not separate the legitimate from the problem failures as I could not conceive of a way to do it. A graph of the data (I am not sure the attachment will make it to the discussion list) shows two high time areas and the 35th minute is late in one and not in the other peak at all. Therefore I cannot have a good answer. I looked at the "Please see". Thanks! I will try this out. -- Robert Lopez Unix Systems Administrator Central New Mexico Community College (CNM) 525 Buena Vista SE Albuquerque, New Mexico 87106
