Possible connection leak

The TimeoutException only happens when the pools are full, i.e. when there are no connections available which is usually an indication that you have a connection leak in which case make sure that all redis clients resolved from the pool are released, which you can ensure by wrapping each usage in a using statement, e.g:

using (var redis = redisManager.GetClient())
{
    //...
}

RedisManagerPool creates new connections instead when full

Another option to is to use the RedisManagerPool which instead of throwing a TimeoutException will create a new connection outside the pool, however this will usually just mask the problem of a connection leak and it will result in a high open/closed connection count.

Increase Pool Resource Settings

If you believe the TimeoutException is due to heavy load you can increase the pool size and timeout seconds, e.g:

var redisManager = new PooledRedisClientManager(
    redisReadWriteHosts, redisReadOnlyHosts,
    poolSizeMultiplier: 40, //connection pool size * no of hosts
    poolTimeOutSeconds: 5); //how long to block for available connection
