Always with the same QNAM object.After a hour I have about 600 running processess and 1024 (which is the user limit) open file descriptors. Do you have a sample program which illustrates this problem? -mandeep Date: Wed, 28 Aug 2013 16:31:34 +0530 Subject: Re: [Interest] QNAM::get() spawns three processess and opens file descriptors which I am unable to close From: mandeepsandhu....@gmail.com To: gsmem...@hotmail.de CC: interest@qt-project.org My problem is that, whenever I call manager->get(), this spawns 3 processess, which I am unable to shut down. After a while (running many requests) there were a huge amount of running processess and open file descriptors. They are consuming RAM and running out of max open file descriptor limit... Every time I call manager->get(request) 3 new processess are spawnt. I am using Qt 4.8.4 on Debian 5. You're not supposed to explicitly do anything with these threads. They're probably started by QNAM for doing the network operations asynchronously and a caller has no control over them. How many such requests are you dispatching in parallel? Looks like you're hitting your systems resource limit. You can either increase this limit (using ulimit), or restrict the number of simultaneous outgoing requests (by doing it in batches). I don't see a bug here. HTH, -mandeep I have also checked the bugtracker and have found a few closed reports:https://bugreports.qt-project.org/browseMaybe you're running out of resouerce/QTBUG-20148 https://bugreports.qt-project.org/browse/QTBUG-20851 _gs _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
