I'm thinking about a java memory leak, but not sure. > Do you know what's going on here ? Well, what made you think "Java memory leak"? Java is userspace. If it's leaking memory so far that the kernel has problems, it would probably: a) Have been leaking memory and causing problems in -957 as well b) Died in the OOM (Out Of Memory) code, rather than in the futex() system call. Yes, poorly written Java code will leak memory like a sieve, but this doesn't smell anything remotely like a memory leak. I agree with Valentin that it's probably the bug report he references. --==_Exmh_1571170801_33600P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXaYp8AdmEQWDXROgAQICog//W9NHC46XJ369nx0njpQhAA+NjAwC5eHA ZO2QCs0NDehe1kgcfEgcrcSb5E/7NMcoflWfjD6I5yOxymrT6u2RtbK9nfWHn5J0 krm6n1rNsCfDgvUWzM/Hjn+IfS9BIxHBeIgQ7SZx3uy7aI8paKgHDgTf6ubctcbc 9kmuHCrtFHZ680j7sXa884rG28wPU3vUESXL7nGVcGp2HpXhQOC1THdRWxsvXmAn bj7qG67LV1/6iFlipTRdigkrAMHr7QWgd44K8tZ72UPEww30LHnwQmbNfShVvyEr 2I5lDsWz00fn4zeJ4IxQ9He/zCIxUi+vm/BizOJWLmc0gc52u5Z3+z6yxI19LJ0o 2rNdVJStREtJg9JPKGVoOb5r24GKXa8DbbP/FERdK9A3Ffbq9/pRXhsGSIJspf1O iMnv1caEdjTYsYFyJSdi2aidh53xucD0qJ2uJQ2Xj6/IHPV+z+wFbZTuW3DavlGJ j53rlNd5bQgKfIaZrb1A9mmnflsVIDF+WOCk1qI4sYAqLAwI7Akr3xP3HFz9Vhx6 dlq3V4OGV/0pTOZUfPP2wuZNdtVzqWt8GFZRAsdEelp6XI9nZO525fe+qODi6Ahj pXRQjr2q8TynXeTkIq9mDXUdDh3ktYARoLPIemq6RMwG+EgYsJzky7W/q3ZY/vkY 2TtoyKJZ6xE= =NEt1 -----END PGP SIGNATURE----- --==_Exmh_1571170801_33600P-- --===============0782258898805104247== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============0782258898805104247==--
