[jira] [Created] (WW-3702) struts2-cdi-plugin - memory never
garbage colleted
struts2-cdi-plugin - memory never garbage colleted
--------------------------------------------------
Key: WW-3702
URL: https://issues.apache.org/jira/browse/WW-3702
Project: Struts 2
Issue Type: Bug
Components: Other
Affects Versions: 2.2.3.1, 2.2.3, 2.2.1.1, 2.2.1
Environment: It happens regardless on Linux and Windows OS
Proble encountered on both Glassfish 3.0.1 and Glassfish 3.1.1
The JDK used is jdk1.6.0_24
Reporter: Marco Malavolta
Priority: Blocker
Every action execution tha thas injected classes consume a small amout of memory that after a while is stored in old-gen. This memory is never released after garbage collection.
After a few days / week, depending on usage, my applications based on struts2 + struts2-cdi-plugin are no more responsive.
This forces me to restart the web server.

-------------------------------------
Thank you a lot for the quick reply
I confirm the same beahviour with devmode=false setting. It takes a lot more time to reach the peak.
I obtained the same results after about 320000 requests.

------------------------------------
Just one thing: in the sample code you've sent, you have the devmode=true setting. Can you confirm that the same memory leak happens when devmode if off?

-----------------------------------
The idea behind is to remove the cache at all, probably it isn't needed as a CDI implementation should do it for us. It can even be worse as a cache duplication.

------------------------------------
Ok, thank you very much for the quick testing. I'll see if I can confirm the results here locally. Any chance you could have a look with MAT or YourKit to see what's leaking? I'll try to have a look here, but I'm currently at work and a bit low on spare time.

Hi to all.
@Maurizio, here my environment specifications

Windows 7 Professional (Microsoft Windows version 6.1 Build 7601:Service Pack 1) 64 bit
Processor: Intel Core i5 CPU 650 @ 3.20GHz 3.33 Ghz
Ram: 6.00 GB
jdk1.6.0_24
GlassFish Server Open Source Edition 3.0.1 (build 22)
-------------------------------------------------------
Today i tried different version of GlassFish with the same application.
I tested these two versions.
GlassFish Server Open Source Edition 3.1 (build 43)
GlassFish Server Open Source Edition 3.1.1 (build 12).
None of them is affected by the issue in my environment, so Maurizio is propably right when he says "it could be also a glassfish issue".
Now I have to check the production environment where we have both GF 3.0.1 (build 22) and GF 3.1.1 (build 12).
In both cases we still experience the same issue...
I'm pretty confused.
Thank you all for the help

----------------------------------------
Hi guys,
@Lukasz
I totally agree with Philip, furthermore I don't believe it fixes the problem.
I have taken a deeper look at this issue last weekend. I also thought that the internal cache could be a potential cause of memory leaks, but setting a breakpoint on the code I realized that there were always 40 objects (not more) inside the cache.
I ran the code example on Glassfish 3.1.1 and unfortunately I didn't experience the problem that Marco mentioned before (I got the usual sawtooth wave).
I also changed the code using the Spring Framework, but the outcome is more or less the same.
@Marco, I could be wrong but can you confirm the java vendor/version?
Have you experienced this issue in other environments (it could be also a glassfish issue)?

-----------------------------------
I added a flag to disable internal cache in CDI plugin, be default now it's disable now. It can enabled again by specifying flag
struts.cdi.useInternalCache = true
Could you check with both settings ?

-------------------------------------
Hi to all.
@Maurizio, I can confirm the java version. I also tried to lower the max memory to 256MB from 512MB for glassfish (with 128MB the old gen was nearly full after starting the server and deploying the application) and the application slows 'til unresponsiveness in about half the time (about 156000 requests in 46 minutes), so the beahviour seems predictable.
I've never tested the application in environments other than glasshfish, cause in my applications I use dependency injection and ejb support.
I think I will take a look at TomEE in a few days. If the problem doesn't affect it, I'll try to promote the switch in production.
Just to know, does any of you has experienced the same problem and can confirm it?

Ciao Marco,
we need some more details, could you start to describe your environment in term of resources: architecture, cpu, memory and so on.
has anyone experienced the issue described by Marco?

Lukasz Lenart closed WW-3702.
-----------------------------
Resolution: Fixed
Fix Version/s: 2.3.1
I leave the cache for now, Weld doesn't provide any caching at this time. It can always be removed in the future.

hi guys,
unfortunately I have no glassfish environment to reproduce the issue.
I'll get ASAP and let you know.

------------------------------------
Regardless of whether or not this works, it seems pretty bad that we need to set a cache flag to false to counter a memory leak.

Just one thing: in the sample code you've sent, you have the devmode=true setting. Can you confirm that the same memory leak happens when devmode is disabled?
