Betreff: Wtr: Memory leak or misconfiguration: Repeated allocation of
very large block
To whom it may concern,
in view of the discussion below may I suggest we remove the --with-gc
option from the Dovecot default options?
Thanks.
Kind regards
Sebastian

Hi Timo,
alright, thanks I will recompile without gc - this is a standard
build option on FreeBSD but I will get the port maintainer to maybe
change this.
Best regards
Sebastian

Dear all,
I am using Dovecot 2.2.19 and I keep on getting the following
warnings in my mail.log file on FreeBSD 10:
Oct 24 10:45:28 server1 dovecot: imap: Error: GC Warning: Repeated
allocation of very large block (appr. size 20480):
Oct 24 10:45:28 server1 dovecot: imap: Error: May lead to memory
leak and poor performance.
I am wondering whether this is a configuration issue (i.e. a
mistake in my current config) or whether I am hitting a bug. What’s
the
best way of figuring this one out? I tried increasing the verbosity of
the logs but it did not really provide me with further information.
I guess you have configured Dovecot --with-gc? I guess it's
possible this is a bug, but it could just as well be a false alarm. In
general I don't recommend/support --with-gc option (and I should
probably just remove it altogether). The easiest and the most usable
way of finding memory leaks is to run with valgrind (which must be
done
without-gc):
service imap {
executable = /usr/bin/valgrind -q --show-reachable=yes
--leak-check=full /usr/libexec/dovecot/imap
}
I'm not aware of any memory leaks right now.
Have you filed a PR for the issue and/or reported this to the
mail/dovecot2 maintainer?
