Due to a change in ssl handling in dovecot between hardy and dapper. The default configuration in dovecot can prevent server loads to rise and become non-responsive when using dovecot. In dapper the login_max_processes_count was not being enforced, however in hardy it is. The attached patch displays in the error log that max login count has been reached, it also puts a comment in the dovecot example configuration file.
Testcase (Should be done in a virtual machine) 1. Install dovecot. 2. Configure ssl with dovecot 3. Run the create users script. 4. Set the login_max_process_count option to 4. 5. Run the client login script. ** Attachment added: "Patch that informs the user of the change" http://launchpadlibrarian.net/14516330/login-max-processes-count-warning.dpatch -- [SRU] connection problems under load with hardy dovecot https://bugs.launchpad.net/bugs/189616 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dovecot in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
