php-java-bridge-users Mailing List for PHP/Java Bridge

I am not sure which component dies. There are no messages left in any  
log files (apache's error_log, /var/run/php-java-bridge.log, etc).

I have posted the bug, and added some more notes from research today.

Which component dies, the java.so or the java backend?

We know that there are issues with Apple's jdk1.4,
which cannot run our bench.php for more than one hour.
But this is a known issue with the apple JVM, the
crash is reproduceable using a pure java test. (It
seems to be a combination of the class gc and the
apple JIT). Which JVM do you use?

Can you please open a ticket for this and attach the
java trace log at the end of the ticket?

Hello-

I've gotten things working, but sometimes the bridge seems to die mid- 
request. The server doesn't have a chance to answer, and no data is  
returned.

I've narrowed it down to the iterator interface over returned Java  
arrays. Here's the offending code:

                 $facets = $facetGenerator->getList($this->value,  
$this->maxRows, $this->sortByFrequency, $this->maxHits);
                 foreach ($facets as $facet) {
			// does nothing, but still crashes
                 }

getList() returns an array of java objects:

public AttributeValue[] getList(java.lang.String attribute_id,
                                 int maxRows,
                                 boolean sortByFrequency,
                                 int maxHits)
                          throws java.io.IOException,
                                 NotFoundException

Here's a tcpflow dump of the bridge comm for that request:

So it seems to me it's somehow getting killed during the iterator.

Now, it doesn't ALWAYS fail. Sometimes it works. I think maybe only  
when EMPTY lists are returned it fails, but I am not positive. Maybe  
that will help you?

Thanks in advance for any thoughts. Please respond to me as well  
directly as I am not currently on the mailing list.

Thanks,
Alan
