IMAP Should Fail More Gracefully When Under Heavy Load
Last updated on SEPTEMBER 01, 2017
Applies to:Oracle Communications Messaging Server - Version 7.0.0 and later
Information in this document applies to any platform.
When IMAP gets overloaded with too many connections, such as when in a fail over situation, all existing connections are failed over to the new standby server as new connections simultaneously, or the subsystems underneath it are being overloaded, it should respond to new connections with a NO [UNAVAILABLE] Service Temporarily Unavailable error rather than trying to process the new connection and the work necessary to handle it.
