Hello,
I have the following Redis-related configuration in my global.asax:
// RedisServer is essentially: server1,server2,server3
var sentinel = new RedisSentinel(AppSettings.GetList("RedisServer"))
{
RedisManagerFactory = (master, slaves) => new RedisManagerPool(master)
};
container.Register(c => sentinel.Start());
container.Register<IServerEvents>(c => new RedisServerEvents(c.Resolve<IRedisClientsManager>()));
container.Resolve<IServerEvents>().Start();
// Third-party rate limiter plugin that leverages Redis
Plugins.Add(new RateLimitFeature(Container.Resolve<IRedisClientsManager>()));
I’m also using the AspNetWindowsAuthProvider with a PopulateUserRoles function set.
One of the nodes in my Redis Sentinel had a scheduled reboot… when that happened, I got a RedisResponseException:
ServiceStack.Redis.RedisResponseException: Zero length response
at ServiceStack.Redis.RedisNativeClient.ParseSingleLine(String r)
at ServiceStack.Redis.RedisNativeClient.SendReceive[T](Byte[][] cmdWithBinaryArgs, Func`1 fn, Action`1 completePipelineFn, Boolean sendWithoutRead)

at ServiceStack.Redis.RedisClient.GetValue(String key)

at ServiceStack.ServiceStackHost.ApplyPreAuthenticateFilters(IRequest httpReq, IResponse httpRes)
at ServiceStack.ServiceExtensions.GetSession(IRequest httpReq, Boolean reload)
After that, the web server looked deadlocked, all subsequent requests were hung until I restarted the app pool.
I know historically Redis issues stem from misconfiguration, am I doing something wrong in the config?
