My use of Spring MVC's DeferredResult class causes Tomcat 7.0.35 to
crash silently
Hello,
I have the following Spring MVC 3.2 code (it uses the DeferredResult
class<http://static.springsource.org/spring/docs/3.2.2.RELEASE/javadoc-api/org/springframework/web/context/request/async/DeferredResult.html>
):
@RequestMapping(value = "getMessages", method = RequestMethod.GET,
produces = "application/json")
@ResponseBody
public DeferredResult<List<Message>> getMessages(@RequestParam
final Long senderId) {
final Long recipientId = memberService.retrieveCurrentMember().getId();
final String messageRequestKey = new
StringBuilder().append(senderId).append(":").append(recipientId).toString();
final DeferredResult<List<Message>> deferredResult = new
DeferredResult<List<Message>>(null, Collections.emptyList());
messageRequests.put(messageRequestKey, deferredResult);
deferredResult.onCompletion(new Runnable() {
@Override
public void run() {
messageRequests.remove(messageRequestKey);
}
});
List<Message> unReadMessages =
messageService.findUnreadMessages(senderId, recipientId);
if (!unReadMessages.isEmpty()) {
deferredResult.setResult(unReadMessages);
}
return deferredResult;
}
This method is polled continuously by an ajax call and it
systematically *causes
Tomcat to crash upon the 9th method invocation*. Note that Tomcat crashes
without any error message.
*I would be very grateful if someone could help me determine the reason why
this code exhibits this behavior, perhaps by giving me tips on how to debug
the app/tomcat.*
Regards,
Julien.

It might be worth simplifying the method while you debug the connection
leak issue.

You're right. I should set the result in another method/thread i.e. a post
method...
Is this related to the memory leaks?

Yes, I meant maxActive, sorry.
Why use a DeferredResult here if you're just setting the result
synchronously and inline anyway? You may as well just remove the key
from the map manually. Am I missing something?

You might try adding in "removeAbandonedTimeout" and setting it really low. It defaults to 300 seconds.

Posted by Julien Martin <ba...@gmail.com>.
@Chuck: thanks for the link. I have read it. Umm... the thing is I don't
close my connection manually. I use Spring. Here is my configuration:
<bean class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close" id="dataSource">
<property name="driverClassName" value="${database.driverClassName}" />
<property name="url" value="${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
<property name="testOnBorrow" value="true" />
<property name="testOnReturn" value="true" />
<property name="testWhileIdle" value="true" />
<property name="timeBetweenEvictionRunsMillis" value="1800000" />
<property name="numTestsPerEvictionRun" value="3" />
<property name="minEvictableIdleTimeMillis" value="1800000" />
<property name="validationQuery" value="SELECT 1" />
<property name="maxActive" value="2"/>
<property name="logAbandoned" value="true"/>
<property name="removeAbandoned" value="true"/>
</bean>
Any idea what I am getting wrong?
@Daniel, I have configured jmx with Spring and I get a numIdle of 0 and
numActive of 2 after the problem occurs. This confirms what you and Chuck
say: my app leaks db connections.
However, I am still not sure why my app leaks the connections. I use the
default Spring configuration...
Sorry: it is slightly offtopic now. I guess this is no longer a Tomcat
question so I should post it elsewhere.
Julien.

Looks like you're leaking database connections, likely by not returning them to the pool. Read Chris' article on how to do it right:

At what point did you run this thread dump? What was the state of your application? How many request were sent to the server? How many responded OK, how many failed?

This thread looks suspicious. Seems like you could be having a problem getting a database connection. Can you include your <Resource /> tags? Also, you might want to connect with a tool like jconsole or jvisualvm and watch the stats for the connection pool. Look at the active, idle counts.

Re: My use of Spring MVC's DeferredResult class causes Tomcat 7.0.35
to crash silently
Posted by Julien Martin <ba...@gmail.com>.

deadlock...
Regards,
Julien.

RE: My use of Spring MVC's DeferredResult class causes Tomcat
7.0.35 to crash silently
Posted by "Caldarale, Charles R" <Ch...@unisys.com>.

That's quite different from a crash. Can you take a thread dump and a heap dump? Using VisualVM or some of the command-line tools, you can monitor the JVM and see if anything odd is going on from that perspective.
http://wiki.apache.org/tomcat/FAQ/Troubleshooting_and_Diagnostics
You may have deadlocked threads, you may be out of heap space, you may have locked up waiting for a database connection, etc. The diagnostic tools should help you figure it out.

Re: My use of Spring MVC's DeferredResult class causes Tomcat 7.0.35
to crash silently
Posted by Julien Martin <ba...@gmail.com>.
Chuck and Daniel,
Thanks for replying. I'll try and provide the information requested.
- The 9th method invocation causes Tomcat to hang. When you issue
requests after that, they also "hang".
- Here is the connector info:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
- Jvm version:
java version "1.7.0_15"
Java(TM) SE Runtime Environment (build 1.7.0_15-b03)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
- My app is 1.6 compatible.
- Platform type and version: Ubuntu 12.10
- APR: I just connect to tomcat through port 8080
Please don't hesitate to tell me if the information provided is not
sufficient.
Regards,
Julien.

And provide the bare minimum of environmental information:
exact JVM version
platform type and version
using APR or not

Can you define "crash" a little better? Is the Tomcat process still running? If so, is it answering any requests? If so, what happens if you send a request to this resource? Do you get a 4xx / 5xx error? Does it hang?
Also, what does your <Connector/> look like?
