What is this error means?
When I am building the index for around 20000 ~ 25000 records, sometimes I
came across with this error:
Uncaught exception "Exception" with message '0' Status: Communication Error
I search Google & Yahoo but no answer.
I am now committing document to solr on every 10 records fetched from a
SQLite Database with PHP 5.3.
Platform: Windows 7 Home
Web server: Nginx
Solr Specification Version: 1.4.0
Solr Implementation Version: 1.4.0 833479 - grantingersoll - 2009-11-06
12:33:40
Lucene Specification Version: 2.9.1
Lucene Implementation Version: 2.9.1 832363 - 2009-11-03 04:37:25
Solr hosted in jetty 6.1.3
All the above are in one single test machine.
The situation is that sometimes when I build the index, it can be created
successfully. But sometimes it will just stop with the above error.
Any clue? Please help.
Thank you in advance.

Here are a workaround of this issue:
On line 382 of SolrPhpClient/Apache/Solr/Service.php, I change to:
while(true){
$str = file_get_contents($url, false, $this->_postContext);
if(empty($str) == false){
break;
}
}
$response = new Apache_Solr_Response($str, $http_response_header,
$this->_createDocuments, $this->_collapseSingleValueArrays);
As I found that, for some strange reason on Windows, when you post some data
and add index, Solr may not be able to receive it. Therefore I added an
infinitive loop and if it does not receive any response ($str is empty), we
post it again.
Side effect: when I open the window console to see it, sometimes it will
prompt:
Failed to open stream: HTTP request failed!
I haven't researched it yet, but the index is built successfully.
Hope it helps someone.

Hi Israel
Thank you for your response.
However, I use both ini_set and set the _defaultTimeout to 6000 but the
error still occur with same error message.
Now, when I start build the index, the error pops up much faster than
changing it before.
So do you have any idea?
Thank you in advance for your help.

Re: What is this error means?
Posted by Israel Ekpo <is...@gmail.com>.
Ellery,
A preliminary look at the source code indicates that the error is happening
because the solr server is taking longer than expected to respond to the
client
http://code.google.com/p/solr-php-client/source/browse/trunk/Apache/Solr/Service.php
The default time out handed down to Apache_Solr_Service:_sendRawPost() is 60
seconds since you were calling the addDocument() method
So if it took longer than that (1 minute), then it will exit with that error
message.
You will have to increase the default value to something very high like 10
minutes or so on line 252 in the source code since there is no way to
specify that in the constructor or the addDocument method.
Another alternative will be to update the default_socket_timeout in the
php.ini file or in the code using ini_set
I hope that helps

"Good Enough" is not good enough.
To give anything less than your best is to sacrifice the gift.
Quality First. Measure Twice. Cut Once.
