Hi Roy, I'm not sure what you are using to create these stacktraces and what they are telling me. Could you try to give some more detail so that I can reproduce them?
That said, we do have some way to limit open zip files using the "felix.cache.filelimit" property (see [0]). I think that might be what you want - however, if you have a way to reproduce the above and there are two open files I would still be interested in knowing about it... regards, Karl [0] http://felix.apache.org/documentation/subprojects/apache-felix-framework/apache-felix-framework-configuration-properties.html#framework-configuration-properties On Fri, Sep 18, 2020 at 4:26 PM Roy Teeuwen <r...@teeuwen.be> wrote: > > Hey Devs, > > I am investigating why our application is sometimes going over the open file > limit of the linux servers we are on, and one of the things I have noticed so > far is that felix actually has an open file for every bundle twice!
