I have here a problem with managesieve. With the login about webmail (roundcube) comes here in the log:

You can always easily reproduce this? Can you get the network traffic logs between Roundcube and Dovecot and reproduce it by sending those same commands manually?

...

--snip dovecot: managesieve-login: Fatal: pool_system_realloc(4294967296): Out of memory dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 10157 returned error 83 (Out of memory (service managesieve-login { vsz_limit=1024 MB }, you may need to increase it))

Looks like there's a bug somewhere.. Doesn't it log a "raw backtrace"?

...

--snap I've increased of 2048M and the same above. then with 4096 M happens the following

--snip dovecot: managesieve-login: Panic: epoll_ctl(add, 61538840) failed: Bad file descriptor dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 9777 killed with signal 6 (core dumps disabled) --snap

Probably related to the first error. It would be helpful to get gdb backtraces from both of them, although from the first one you couldn't without patching + recompiling Dovecot. But from the second one I think you can get a core dump with:

service managesieve-login { executable = managesieve-login -D }

Then you can do something like:

gdb /usr/lib/dovecot/managesieve-login /var/run/dovecot/login/core

Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning. [Churchill]

You'll of course need to have the core file first. Instead of:

...

...

dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 9777 killed with signal 6 (core dumps disabled)

It should say (core dumped). Besides the executable change, you'll need to run "ulimit -c unlimited" just before dovecot binary.

If I run "ulimit -c unlimited" no problems more with Managesieve Login over Roundcube:

But the same:
