Hi Wido and Florent, After going back into the error-report with my new knowledge, I think I found the problem. It is the finalizer in com.ceph.rados.Rados.java Commenting out the finalize() method solved the problem. I have no idea why it causes all this trouble, and I don't know if commenting it out is the solution for every use case, but I think I can do without the finalizer. I tried different versions of jna, including the latest one jna-4.2.1. That works. --- You asked: ceph --version ceph version 0.87.2 (87a7cec9ab11c677de2ab23a7668a77d2f5b955e) librados-config --version ceph version 0.87.2 (87a7cec9ab11c677de2ab23a7668a77d2f5b955e) --- One more thing When recompiling rados.jar according to the instructions on https://github.com/ceph/rados-java I encountered one test-error: testCreateFormatOne(com.ceph.rbd.TestRbd): Failed to remove image imageformat1 This may have to do with ceph.conf-setting: rbd default format = 2 rbd info rbd/imageformat1 rbd image 'imageformat1': size 10240 kB in 3 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.1f6a9d7fdcc233 format: 2 features: layering, striping stripe unit: 4096 kB stripe count: 1 I don't fully understand, as the "format 2" should have failed the previous test: assertTrue("The image wasn't the old (1) format", oldFormat). and this documentation is obsolete: http://docs.ceph.com/docs/hammer/rados/api/librados-intro/#getting-librados-for-java --- Thanks again! It great to get some friendly support; it kept me searching... Best Regards, Kees Op 28-12-2015 om 15:28 schreef Wido den

Even if I do not upload a file, the error occurs after a couple of minutes... Strange!Did you open a RADOS context or connection in that case? What version of librados are you using on the system and what is the Ceph cluster running? Wido |
