Hello,
when I try to convert from mbox to mdbox with dsync with one user it
always panics:
# /opt/local/bin/dsync -v -u userxy backup ssh root@minerva1
/opt/local/bin/dsync -v -u userxy
dsync-remote(userxy): Panic: Trying to allocate 2147483648 bytes
Well, this is clearly the problem.. But it's difficult to guess where
it's allocating that. I'd need a gdb backtrace. Does it write a core
file to userxy's home dir? If not, try replacing dsync with a script
that runs "ulimit -c unlimited" first and then execs dsync.
http://dovecot.org/bugreport.html tells what to do with core once you
have it.
Alternative idea: Does it crash also when dsyncing locally?
gdb --args dsync -u userxy backup mdbox:/tmp/foobar
run
bt full
Sorry, this problem is gone, I cannot reproduce it any more, neither
locally nor with remote dsync. I found out that the user has one huge
mail in his drafts folder with a 1GB video object attachment, but he
surely never could send this mail because the mail size is limited to
50MB.
Greetings, Jürgen
