Broken pipe exception
Hello All,
I've run into another problem related to xindice. Its a remote site that
we dont have access to, but they have sent the error log, which i have
added below. We have a central monitoring system that accesses various
xindice databases running on tomcat installations.
I am able to access the web interface of xindice on that site without a
problem, and have ensured that the request information is available.
but the php rpc call
$result = xu_rpc_http_concise(
array(
'method' => "run",
'args' => $params,
'host' => $host,
'uri' => $uri,
'port' => $port
)
returns 0 results from this one particular site, and causes the
exception shown below in that sites tomcat logs.
Any ideas? I tried increasing the timeout since the db has a large
number of records, but that didnt help.
The parameters to this rpc call are fine.
thanks & regards
Rohit

Re: Broken pipe exception
Posted by Todd Byrne <by...@cns.montana.edu>.
The fix to that exception is in SVN, but the only way to get to that
code is through an HTTP_GET method. The ugly browser is the HTML
database view not XML RPC.
My hunch is that you just need to do a normal PHP open on the URL and
read in the contents of the file to see if the database is still
running. My PHP is a bit rusty otherwise I would give you an example.
If you get the exception in the future its just the xindice not finding
the correct collection: http://localhost:8080/xindice/?/asfd will throw
the exception.
