When I tested migrating users from server A to server B I only used a copied a small number of users (about 30) only with less than 200MB of mail. Instead of copying the existing quota database I pulled the quota setting from the old server, made sure the settings were sane, and built a new file for each user. The first line contained 0 and the second line the quota in kb. Example for a user with 50MB limit: [EMAIL PROTECTED] root]# cat /var/lib/imap/quota/a/user.anthonylegarde 0 50000 'quota -f' ran just fine but when it finished it set the disk usage to double of the actual amount. A second run of 'quota -f' set the disk usage to the proper value. I thought thiswas odd but being on a schedule I had a working solution, so I ran with it. > I'm not sure about the open files limit.

When I moved user data from the old server to the new, the 'quota -f' run died with a 'too many open files' error during the first few hundred users. I did a 'ulimit -a 65536' as root before becoming cyrus and doing 'quota -f'. This made this error go away but now I get the seg fault after the last user has been processed but before the process is complete. Because 'quota -f' takes nearly an hour to run it is difficult for me to do any troubleshooting. There are few opportunities when I can shutdown the cyrus-imapd processes to run 'quota -f'. And I cannot replicate the problem on a smaller box that has a smaller number of users.... If it is safe to run 'quota -f' with the cyrus-imapd processes running I try to find the problem but I need to know if this is safe.
