Tridion Web UI shows error Not enough Storage to complete this action

Question

I had seen that Tridion UI is displaying the error

Not enough Storage to complete this action.

I checked the event log of Tridion and I see a series of errors

• The number of render failures has exceeded its specified failure limit of 0.
• Not enough storage is available to complete this operation.

Log associated to number of render failures can be found below. I have searched in net but could not find any information on this. This issue is reoccurring in the environment. What could be the reason. Any suggestions to fix it.

We are using Windows Server 2008 R2, and Tridion 2011 Sp1.

Component: Tridion.ContentManager.Publishing Errorcode: 0 User: NT AUTHORITY\SYSTEM

You are mentioning two completely different errors here, which might have a relation in the end.

The number of render failures error is one triggered by a Publish Transaction which contains multiple render actions. Something like Publishing a Structure Group, you are then Publishing all Pages in that Structure groups, which will lead to multiple Pages being rendered in that single Publish Transaction. If some of those Pages fail rendering (a template error for instance), you will generate a render failure. By default the number of render failures allowed in a Publish Transaction is 0 (it can be increased in the Advanced tab of the Publish dialog).

So simply put, this error was just telling you something went wrong in the render action of a Page or Component. If you double click the Publish Transaction in the Publish Queue, you can open it and see the details in the Processed Items tab.

Now onwards to the other error, Not enough Storage to complete this action.. That is one I haven't seen myself before, but judging from the comments and you mentioning it was resolved by restarting the services, I think you might have been running into a COM+ memory issue.

First thing to make sure is that you have enough resources on the server, or if it is a heavily used server (a lot of active users and/or a high Publishing load), you might consider out scaling the Publisher to a separate machine, so you don;t have to share resources between the UI and Publishing.

Then next you could look at configuring application recycling for the SDL Tridion Content Manager COM+ application. In the console tree of the Component Services administrative tool, right-click the COM+ server application you want to be recycled and then click Properties.

On the Pooling & Recycling tab, you can enter a value for Memory Limit (KB). A valid value would be something less than 10% of your total amount of memory, a bit depending on the usage of that server. This is something you might have to tune, so it might take several tries/changes to get it right. One important thing to understand is, that once the COM+ application reaches the specified memory limit, it will start the recycling process. That means it will stop taking calls in the current process and start a new one. The memory of the process which is about to be recycled cannot be released instantaneously, so it might take some time for it to be all freed up. So it could happen that at some point you have two or even tree processes active at one time, which means you should have an adequate amount of memory for all those in your server (which is why you do not want to set the memory limit too high).

Don't bother with the Lifetime Limit or Expiration Timeout, they are not really relevant because of how this COM+ application is used.

As for the possible relation between these two errors, a failure in a Template render process, can lead to an unfinished process which could even lead to a memory leak. But even without a memory leak, there will still be memory in use which might not be released instantly. So the render failure could have just been the trigger for the other error. Although more likely it could also have been your Publish Transaction which by default caches, and thus requires more memory than a Publish Transaction which contains only a single item.

One last remark, 4GB of memory for a Tridion server I now a days consider on the low side. Certainly of that machine is running the Publisher too. It's a bit depending on whether this is a dev or a production server, and how much it is being used of course, but I would consider doubling the amount of memory in that machine or consider outscaling the publisher.
