Transaction Prepare fails: unable to create mutex (isolated storage)

[Jochen Zeischka]

Did anyone see this before? Occurs when using Raven.Client 2.0.3.2380 in an IIS hosted environment.

System.Transactions.TransactionAbortedException: The transaction has aborted. 

---> System.IO.IsolatedStorage.IsolatedStorageException: Unable to create mutex. (Exception from HRESULT: 0x80131464)

I would assume that any app pool identity would have rights to use Isolated Storage? Other ideas why this fails?

Haven't seen this before

Is IIS set to load the user profile?

No, Load User Profile is set to False.

[Oren Eini (Ayende Rahien)]

Same thing when set to true?

No, it worked this time!

But, interestingly, I have other app-pools using the same kind of transaction (local MSMQ + RavenDB) which do not have this issue and are not loading the user profile. Suddenly this issue appeared on this virtual app...

[Jochen Zeischka]

I turned load user profile off again, and now it works without using the profile as well... No clue.

[Jochen Zeischka]

Sadly, this morning this exception appeared again and loading the user profile does not make any difference anymore. We are currently not able to commit transactions on this environment.

[Oren Eini (Ayende Rahien)]

this is some sort of permissions issues on the machine.

FWIW, upgrading to 2.5 should resolve this

It does not seem to be a permission issue. We have intermittent failures (most of the time actually, but not always).

Running with admin credentials does not solve the issue.

[Oren Eini (Ayende Rahien)]

Is it possible for you to upgrade? That is the easiest fix.

[Indu Alagarsamy]

This error is still occurring intermittently after upgrading to 2.5.2916 of RavenDB (server and client) 

Hosting on a regular windows service. 

Thanks,

Change DocumentStore.TransactionRecoveryStorage to an instance of LocalDirectoryTransactionRecoveryStorage

[Indu Alagarsamy]

Hi,

I am trying to understand why is this error occurring and somewhat intermittently at that.

What are the advantages of using LocalDirectoryTransactionRecoveryStorage over the IsolatedStorageTransactionRecoveryStorage?

When do we use what? 

Can you please clarify?

Thanks much,

Indu Alagarsamy

Isolated Storage has issues like the mutex, Local dictiory doesn't have those issues.
