[tauruslib-devel] client dependent memory leak

[Zbigniew R. <zre...@ce...>]

Hi Roberto!

I'll move this discussion to the taurus-devel mailing list (recently the 
Sardana and Taurus had separated their SourceForge infrastructure)

Here at Alba we use the following versions of the software:

* server side:
** OpenSUSE 11.3 32 bits
** Tango 8.1.2.c + 4 patches from the Tango website
** PyTango 8.1.4

* client side:
** OpenSUSE 11.3 64 bits or OpenSUSE 12.1 64 bits
** Tango 8.1.2.c + 4 patches from the Tango website
** PyTango 8.1.4
** we try to follow the develop branch of Taurus (it is at least 3.6.0)

AFAIK we do not observe the memory leaks. But just in case I will leave 
a taurusform with few attributes and devices running overnight.
Tomorrow I will get back to you with the results.

Meanwhile could you provide us more information:
* how many attributes / devices (models) do you have in your form.
* what type of attributes do you use? SPECTRUM, SCALAR, DevFloat, 
DevLong, etc...
* do the attributes emit events? are they polled by the server?
* are your models coming from the default TANGO_HOST of the client 
machine? or you specify the model names with the explicit tango database 
and port?
* how do you choose them? specifying the models as the execution 
parameters? or from the model chooser? or with the drag&drop mechanism? 
or maybe you programmed taurusform GUI with the hardcoded models?

Cheers,
Zibi
