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 tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland www.oetiker.ch tobi at oetiker.ch +41 62 775 9902 -------------- next part -------------- An HTML attachment was scrubbed...
