100 MB RAM per clinet in an imap-proxy setup ...

[Tobias Oetiker]

Hi All, 

I spent some quality time yesterday, tuning dovecot on a server which serves as an imap-proxy in front of a zimbra setup 
the imap proxy does ldap client-cert authentication and works well. 

BUT 

I found that the imap-login processes seem to gain 100 MB per connection they are accepting ... this seems pretty hefty. 

It does not seem to be a leak, since the setup is stable when client_limit and process_limit are set appropriately. 

Any ideas what part of the code I should be looking at ? Or is this a configuration problem ? 

cheers
