Hi all,
I'm having problems with memory in config service. I increased vsz_limit to 10GB but continue with this errors when try to reload or restart dovecot:

config: Panic: data stack: Out of memory when allocating 2147483688 bytes
master: Error: service(config): command startup failed, throttling for 2 secs
config: Fatal: master: service(config): child 5512 killed with signal 6 (core dumps disabled)

Dovecot has a lot of certificates TLS configured (SNI) (about 3k), but if I check the size of all of them is aprox 170MB on disk.Why does it need so much memory to boot? Is normal?



service config {
vsz_limit = {{ vszlimit }}
}
Hi!

Can you send your doveconf -n output?
