When a connection to Redis is lost, TMM attempts to reconnect with up to five retries. If all retries fail, TMM gives up and will only retry upon receiving session requests.
In the current implementation, if TMM's connection to Redis fails, it only attempts to reconnect when a new Session DB API call is made. Ideally, TMM should reconnect to Redis immediately, so Session DB callbacks (such as when Redis deletes an entry due to a timeout) can be handled correctly by TMM.
1. Bring down the DSSM. 2. TMM attempts to connect to Redis with up to five retries. 3. If the connection fails, TMM gives up and will only retry when there is a session request at TMM.
None
The MAX retry condition has been removed. With this fix, TMM will continuously retry to connect to Redis.
