I've migrated my config and user data from a fedora38 system to a fedora40
system with postfix-3.8.5 and now vacation is segfaulting for some users. I
don't understand why it's failing for some while succeeding for others.
Aug 8 12:44:00 cipher postfix/local[403497]: 280B665FBD: to=<61...@example.com>,

Any idea what could be wrong?
I have removed the .vacation.db file in case it was somehow corrupt. I've
also verified file ownership.
# ls -l .vacation* .forward
-rw-r--r--. 1 61104 users 40 Apr 15 2022 .forward

"|/usr/bin/vacation 61104"
Is 61104 a user account name, like this?
postmap -q 61104 unix:passwd.byname
Historically bad choice for usernames, but yes, exactly:
postmap -q 61104 unix:passwd.byname
61104:x:3400:100:Premier Medicine Hat:/home/61104:/bin/bash
How is this different form the 'working' accounts?
That's what I'm trying to figure out. I've also noticed that sometimes it
succeeds for the same user and fails other times.

Bad memory sounds like a logical explanation here, and this is a new
server, but I just wanted to be sure I'm not missing something else.
It's a relatively active server and haven't noticed any other segfaults
(other than with vacation) after about 48 hours of operation.
Does `coredumpctl` list the crash, and can you get a backtrace?
`vacation` does not seem part of Postfix’ source. From what package is it?
Kind regards,
Paul
