I have two smtp servers that sit behind alteon load balancers which perform health checks every 5 seconds to make sure the servers are up.
but these health checks are causing a lot of messages like this to appear in the log files 2007-11-14 12:18:17 SMTP protocol violation: synchronization error (input sent without waiting for greeting): rejected connection from H=[212.57.34.221] 2007-11-14 12:18:22 SMTP protocol violation: synchronization error (input sent without waiting for greeting): rejected connection from H=[212.57.34.220] 2007-11-14 12:18:23 SMTP protocol violation: synchronization error (input sent without waiting for greeting): rejected connection from H=[212.57.34.221] 2007-11-14 12:18:28 SMTP protocol violation: synchronization error (input sent without waiting for greeting): rejected connection from H=[212.57.34.220] what is the best way to avoid such messages? do i need to increase the health check period on the load balancers to 30 seconds instead of 5? thanks, Oliver -- Oliver Howe Senior Systems Administrator Tel: +44 (0) 79 7420 6484 Fax: +44 (0) 20 7664 7878 Spider Networks - the power behind interactive web communications - www.spider-networks.net -- Confidentiality Notice: This email is confidential and may also be privileged.
