Trying to test an improvement to ehcache performance, I ran into this error:

Code:

Any ideas on what the problem might be and how we might fix it?

We are using Terracotta 2.6.2 with the tim-ehcache 1.1.3 module - we were told to upgrade from tim-ehcache-1.1.2 to 1.1.3 and put the following line in our properties file:

'ehcache.lock.readLevel = NO_LOCK'.

This is our tc.properties file:

Code:

ehcache.concurrency = 61
 l2.l1reconnect.enabled = true
 l2.l1reconnect.timeout.millis = 15000
 ehcache.lock.readLevel = NO_LOCK

And this is our tc-config.xml:

Code:

Certainly looks like a bad locking level, although everything you mentioned in terms of tim versions, the tc-config, and the tc.properties values looks correct to me.

The stack trace there should only be entered if the lock level is NOT nil (=0) so I don't understand why you are seeing that.

Someone will take a closer look and contact you.

It was suggested that we delete the tim-ehcache-1.1.2 jars from the modules directory, but when we did so, the tim-hibernate-3.2.5-1.1.2 module gave us dependency errors - it had apparently needed them. This might have had something to do with our errors in the first place, but how do we get around it?

Can we use tim-hibernate-1.1.3 with Terracotta 2.6.2? When we delete the tim-ehcache-1.1.2 jars from the modules directory, tim-hibernate-1.1.2 complains about dependencies, and 1.1.3 says it’s for Terracotta 2.6.4 on Forge.

Do we need to upgrade to 2.6.4 and tim-hibernate-3.2.5-1.1.3 and tim-ehcache-1.1.4? Are there going to be dependency problems there too?

Ah, I see. tim-hibernate-3.2.5-1.1.2 depends on tim-ehcache-1.1.2 but there is no 2.6.2-compatible version of tim-hibernate-3.2.5-1.1.2 available.

Looks like there are two options:
1) We could release a new tim-hibernate-3.2.5 version dependent on tim-ehcache-1.1.3 (unfortunately the numbering would be goofy).
2) You could bump up everything to 2.6.4-compatible versions. You should be fine moving everything to 2.6.4 as we did release versions of all TIMs along with 2.6.4.

We'll look into upgrading to 2.6.4 (been meaning to do that soon anyway), but in the meantime, if there's a chance you guys could release a 1.1.3-compatible version of the tim-hibernate-3.2.5 module, that would be great.
