Experiencing frequent java.lang.OutOfMemoryError: PermGen space errors

[Scott Murphy]

Could this have to do with the fact that groovlets and gtpl files are
not compiled?

If you keep running a groovlet over and over, will you eventually fill
the PermGen space?

[Guillaume Laforge]

Hi Scott,

You're getting OOME / PermGen errors in production or in development?

Hi Guillaume,

I am getting them in production.

I was getting them in development, but was able to tweak the startup
settings.

[Guillaume Laforge]

Groovlets and templates should be compiled once, the first time they are accessed.

So it's weird to hear about PermGen issues in production -- whether in development that could happen since you reload for each change you make.

There might be some reloading issues, in the Groovy script engine.

Someone raised an issue about that again recently.

Perhaps that's related.

Could you show a stacktrace that you get, in case there's more information than the OOME?

Should I try upgrading my version of Groovy? Currently I am running
1.8.1.

Not really much on this one:

A serious problem was encountered with the process that handled this
request, causing it to exit. This is likely to cause a new process to
be used for the next request to your application. If you see this
message frequently, you may be throwing exceptions during the
initialization of your application. (Error code 104)

[Scott Murphy]

I upgraded from Groovy 1.8.1 - > 1.8.3 (Still experiencing PermGen
errors)

[Scott Murphy]

I am still getting clobbered by these things and it seems to be
getting worse (happens after my app has been running around 3
hours). Could having methods in my Groovlets cause this?

hello.groovy

def method() {
println "hello"
}

method()

[Guillaume Laforge]

That's weird, it's certainly not just simple method calls that cause that.

But I can't really help you here.

What are you doing special in your app?

Are you doing lots of new GroovyShell().evaluate(), creating classes on the fly or such things?

[Scott Murphy]

I do not do any GroovyShell().evaluate()'s on my site and I don't
think I am creating classes on the fly (Do anonymous inner classes
fall into that category?)

My site gets a decent number of pageviews (200k+/day). I usually get
a PermGen error after an instance has been running for ~ 3 hours. It
never happens quickly.
I do have a lot of external dependencies (jars) Spring Framework,
Spring Security, Spring Social, Map Reduce (hadoop), etc.

Here are a few questions:

1. Are Groovlets recompiled on every execution?

I see in https://github.com/groovy/groovy-core/blob/master/src/main/groovy/servlet/GroovyServlet.java
that the script needs to be run every time:

return ((GroovyScriptEngine) getDelegate()).run(scriptUri, binding);

Unless the GroovyScriptEngine caches the script?

2. Do simple methods in a Groovlet like I mentioned previously result
in the creation of a anonymous inner class?

myGroovlet.groovy

def method() {
println "hello"
}
method()

3. What would be the result of having a class within a groovlet? Does
this class get created every time the Groovlet is run?

myGroovlet2.groovy

class Person {
String name
}

def method() {
println "hello"
}
new Person()
method()

4. Is there any impact in having includes in gtpl pages?
<% include '/WEB-INF/gtpl/includes/footer.gtpl' %>

No, they're just like Java's.

The groovlets are turned into scripts which are compiled once and cached by the underlying groovy classloader.

So normally, they really just need to be compiled once.

 

2. Do simple methods in a Groovlet like I mentioned previously result
in the creation of a anonymous inner class?

myGroovlet.groovy

def method() {
   println "hello"

No.

   String name

4. Is there any impact in having includes in gtpl pages?
<% include '/WEB-INF/gtpl/includes/footer.gtpl' %>

The include mechanism is the one from the servlet engine.

So Gaelyk is just inserting the output of the included template in the resulting output, but since the templates and groovlets are supposed to be compiled just once, it's not creating any new class or anything like that.

So... I'm not really sure what's going on here.

Didn't you mention you were using Spring?

Are you using the lang:groovy namespace?

Another are to investigate...

So templates and groovlets should be compiled only once, so they won't take more perm gen later on.

But I remember some bug report saying that sometimes the templates were recompiled as there was some problem with the logic of recompilation or something like that.

So I've just had an idea here to check if this assumption is true or not.

Could you please add a log statement like log.debug "Current groovlet/template ${this}"?

Look at all such statements, and the toString() should be the same for the same groovlet or template. 

Otherwise that means re-compilation happened.

And if recompilation happens more than needed, after a while, it's going to eat up perm gen.

(I'm really looking forward to when the JDK won't have perm gen anymore...)

And please report me back about that.

I may have a look back at some of the bug reports on this topic, and see if we can cook a snapshot of Groovy that fixes the problem, and then integrate that to Groovy it there was indeed a problem there, and that it's fixed and working for you.

[Guillaume Laforge]

Could you make a similar test in production especially?

In local mode, there's an automatic reloading in place, but it's not the case in production.

Although if nothing changes locally, it shouldn't recompile the template and groovlet anyway.

I'm thinking that there might really be still a problem with the reloading strategy of Groovy's own groovlet and template servlets here.

I'll definitely have to investigate that further.

Yeah, same thing happens on production. Do you think using a
different version of Groovy (older1.7/newer1.9beta?) will make my
problems go away temporarily?
These PermGen errors really suck as they make me kind of helpless. I
am currently using Groovy 1.8.4

So it seems we really have a problem with the reloading / recompilation logic, which makes the templates and groovlets reloaded although no changes have happened.

I'll try to investigate the problem soon.

Pretty likely to be the problem you're encountering:

https://jira.codehaus.org/browse/GROOVY-4975

Don't you think?

Guillaume

[Scott Murphy]

That sounds like it would be more problematic if it was fixed, no?
That sounds like the problem in that ticket is that classes are not
reloading vs our case here is that our scripts are constantly
reloading?

[Guillaume Laforge]

I actually think both are linked.

So let's watch that issue :-)

Hopefully we'll find what's going on.
