Closed Issue: Load balancing is not working properly in distributed environment. [10058]

jsrajjan — Thu, 16 May 2013 09:09:48 GMT

First of the thanks to ronischuetz and team for the efforts that you are putting...

I have a little problem using the Sharedcached, hope you guys can help me out. I am trying to use sharedcache with distributed servers. Everything works well distribution (adding into multiple server), load balancing when all the servers online. But if one of the server goes down, even when the application(client) starts, the load balancing is not working good. Caching is not happening 100% at the online server.

Thanks
Rajjan

Indexus.cs line 175

The COM.Handler call in this method should be wrapped in 'IF #trace' like the other trace calls.

Created Issue: Memory Hike & Replicated Caching Issue [15860]

nish — Thu, 12 May 2011 10:29:59 GMT

We have installed 3.0.5.1 and implemented Replicated Caching between two server for one of our c# based application. We are using .net version 2.0.50727.

We are facing two issues as below:

Issue 1: We have set CacheAmountOfObjects="500" but when we ran load test then we are observing that memory is not getting free. It goes above 1GB and ultimately we have to restart SharedCache server to release memory.

Issue 2: We have configured replicated caching between two server. After sometime of usage, we can see that objects are not in sync between two memcache server. This behavious is easily replicable when we run load test.

Any help to sort out above mentined issue would be highly appreciated as we are soon planning to deploy solution on our production environment.

Closed Issue: Race Condition in TcpSocketConnectionPool.GetSocket() [14083]

chadfawcett — Mon, 11 Oct 2010 00:41:52 GMT

A race condition can cause an unhandled exception in multi-threaded client applications. Between the checks to see if there are available sockets and the dequeue() call another thread may lock and grab the last socket connection. I have a patch to address this issue which I will upload as well.

Exception stack:

Unhandled Exception appears: Queue empty.

Created Issue: MultiAdd(IDictionary data) vs MultiAdd(IDictionary data) [14415]

Would it possible to have a MultiAdd and MultiGet based on T rather than byte[]?

This would seem to follow the Get<T>(string key) pattern established

Hi.

Same issue to report here. SharedCache is taking about ~700Meg, even though I only have 27 Meg of cached data.
I've got logging disabled on our configuration, and the issue is still there.

How is getting on this issue? Has someone discovered something new about it? I have the same problem with the memory limit. My config is as following:

Is there any problem with it? Perhaps ServiceCacheCleanupThreadJob is very high?

Thanks in advance.

Hi Kent,

thanks for sending me your files. i will try to response asap by tomorrow and provide more information.

I removed your previous post with code then i plan to provide a download file.

Same problem.
We've used the official release version and recompiled the latest version.
We're also using 127.0.0.1, should we use 0.0.0.0 instead to bind to all network adapters ?

Commented Issue: Retrieve Cache after reboot [9466]

fryedfish — Fri, 04 Dec 2009 11:36:26 GMT

Hi,

I've seen that after server rebooting all datas contained in cache are removed from memory.

Is possible to retreive this data?

Thanks!

fryedfish — Fri, 27 Nov 2009 14:53:50 GMT

On first access a race condition is apparent in the Property Get method for Servers, ServersList, ReplicatedServersList and ReplicatedServers, for the IndexusSharedCacheProvider and IndexusServersharedCacheProvider. Servers.Count value can yield inconsistant values also the same server can be added to the list twice.

lock and load from config in static constructor would fix
