Indexing processor state is Closed.
ChangeNotificationDatabase (underlying mechanism for catalog content indexing queue) calls (used by InDatabaseQueue<T>) produce deadlocks in database: deadlocks may occur during different calls like GetStatus(), Enqueue(), Dequeue().
After that I have to reindex full catalog (that takes me about 40 minutes) because indexing proccessor becomes "Invalid"
But that is not working in my production solution.
Could some take a look into deadlocks issue?
As I see the problem is inside dbo.ChangeNotificationXXX stored procedures that are being called in concurrent manner and each dbo.ChangeNotificationXXX procedure makes updates to several tables (processors, connections, queue it self).
Probably I have outdated database(stored procedures like dbo.ChangeNotificationXXX)?
My MSSQL version is: 11.0.2100.60

I have just setup following experiment:
Input:
- Commerce Manager Web application = App1(stopped)
- CMS Front site = App2 (stopped)
- "Catalog Index" processor invalid
Actions:
1. Start App1
- App1 starts to do notification "heartbeats"
2. Start App2
- App2 starts to do notification "heartbeats"
At some moment App1 and App2 do concurrent heartbeats and deadlock occurs, as a result App1 stops doing "heartbeats" (in other cases it can produce another error, like invalidating of valid processor)
Please check trace(SQL) and app logs:

Could someone take a look? My first post about the problem was more than month ago:)

Have you created a support case for this problem?
We are also experiencing the probleme with Indexing processer is closed. I haven't seen the ERROR log from the QueueWrapper, but I guess it could still be the same problem.
My experience is, that EPiServer looks at these forum posts, but doesn't necessary take action on them. However the support cases are monitored and action is taken at some point.

Hi Andres,
QueueWrapper is my custom class that wraps default implementation from EPiServer framework and does logging if error occurs. Default implementation does not log errors, so you even can't know that they do happen:)
About support case, I personally haven't, but another guy from our dev team has I suppose.

Closed state = need to reboot IIS because you can invalidate/recover in such case (what I definitely want to avoid)
Here is some log:
2014-04-23 23:43:48,729 [5] ERROR Jula.Common.Events.QueueWrapper: wrapped error

Jula.Common.Events.QueueWrapper - is custom class that wraps InDatabaseQueue<T> from commerce f/m and just adds logging abilities.
I suppose this error makes indexing process closed.
Is it a bug? or some configuration issue?
