Could not call the function

[mr_jingles]

Hello everyone,

i am using the PHP Gearman Client and getting the following error:

"Warning: GearmanClient::runTasks(): Could not call the function in
[...]"

I have been searching the web for a while but didn't find any hint.
Maybe someone of you has an idea or some helb for me.

Thanks in advance,
Benjamin

I have never encountered this myself. Please provide the version of
pecl/gearman and gearmand you are using. Also, please provide the
snippet of code for the addTasks and runTasks calls. We can better
help you with that information.

Hello Herman,

thx for reply.

This is the environment:
extension version 0.8.0
libgearman version 0.14
PHP Version 5.3.6-13ubuntu3.3

The code is an huge abstraction layer, but nothing special. Using
priority and running in foreground.

I let you know, if I have some further information.

Regards,
Benjamin

I took a look at the pecl/gearman code. The warning is generated when
the internal call zend_call_function() returns a failure. This can
occur in two places: 1) the worker callback 2) the return callback.
Are you defining the callback with a string, array or anonymous
function?

[mr_jingles]

I had all callbacks with a php callback as an array (array($this,
'funcname'). As I removed them, except the on complete one, the
failure doesn't appear anymore.

It definitely sounds like a scope problem. Were any of the callbacks
referencing a protected or private function that the abstraction layer
did not have access to?

[mr_jingles]

No really, the callbacks referenced to another public method which has
access to a protected attribute of the object.

I just had this too, but it came after a number of successful callbacks.  

Is PHP garbage-collecting the array($this,'method') passed as the function argument?  The error message lacks any function name (and also doesn't have "[undefined]" to indicate a missing pointer), so I suspect the callback data is being overwritten at some point.

Hi All,

I had the same problem and I found the answer as well. See it here:
