Hmm. Dovecot v1.0 updates the dovecot-uidlist file only by recreating the entire file. Those files have a lot of corruption in them. There are a lot of NUL characters in places where Dovecot simply couldn't have written them. There are also several garbage characters that Dovecot couldn't have written unless its memory was badly corrupted. Aren't you seeing any other crashes and such? If these uidlist files are getting so badly corrupted, it's weird that you're not seeing all kinds of other random crashes. Are you using Dovecot's index files? Here's one interesting part in the bad uidlist (replaced NULs with spaces): 488 1225345601.P24822Q15.xayide.jones.dk:2,S 489 1 ones.dk:2,S 490 1225345603.P24822Q17.xayide.jones.dk:2,S That really looks like the corruption has happened after Dovecot already wrote the file.
