It says nothing at all about a memory leak, and as I already mentioned, if Java was leaking memory, it would almost certainly have been leaking memory on a previous kernel. The important part almost always isn't the running process, it's the kernel stack traceback, which in this case has 'futex' scribbled *all* over it. General rule of thumb: If you get more than one crash that has a similar traceback that points at a specific syscall, or file system driver, etc, the bug is almost guaranteed to be in that code. If you get a rash of crashes with *different* tracebacks, you probably have some other code that's overlaying memory. --==_Exmh_1571235402_33600P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXacmSgdmEQWDXROgAQJiWA//aZA1eQ8LxFXSuifQmUZ34mE3gFbjZtMJ 4oByoi+BoddA74Gfave/MMgiJ1r4nQ6zY8M5DVvX99XpSr3ZYBirKylfbIQ/lyK8 r+qehvt91yFKw9f7WlG+LdgkqC+WZI0iTp38YZl+cldM0NI2e9PuCXf809WKIa/K gQOjAfYfElbEzFlEP+6o8WlNjmSIMea89+o8U/QRWDICdE4DFgj15nQaV6oXCE5Q YAM+vb6SRaOTPtqXjRsE6PahevE4gfiSKZuKOKi5+usxsaOWGUlMU1FeYyN97Tj5 wLJ5IeHgdue9jsosG184Dnn9fnIEc0Rzen9sQsZmEFTX7zbmn1iGnuHis8J6vQTo z+lHDnVaPB30f4mDuYBblvX7+z3NtYwYkhrj/OpRr34l7cQUbSvtTvM7SGRGE2Gh vbycmC9pYaH8Cmd/Sk4i577nYxkwHHPzEMKviY4kLZBNdt72yFTvHhfqAd30ZpWP QOMr6bPu5FLGYT7QX0spYBJpVsNdrg0PrzHF+o3rncVW+3usjsw1RGqDcpyo6dIb Pph9oUFKdML/6rbBrLRwryFNEYyMyFe+rKVax5lEg3YDITwhpm4Y/wYYj+T0zCNf oT7TmcCahNxYwd8EoZevgCcpQvI2YZl2XYUbie46+KRpqBAKe5kZdehO6zt535J4 1S+d2s2g3Q8= =PP8H -----END PGP SIGNATURE----- --==_Exmh_1571235402_33600P-- --===============8053203276815893898== 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 --===============8053203276815893898==--
