[Dovecot] Out of memory/Managesieve

[Jim Knuth]

Hello,

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

--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))
--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

How can one solve then this?
Any ideas greatly appreciated. Thanks.

Mit freundlichen Grüßen,
with kind regards,
