From the looks of it, one or more jar/zip files are being opened by the VM, changed on disk, and being accessed again from the VM object. Because the VM uses mmap to open zip files, once the file contents change, there are memory errors. This is a known issue (in OpenJDK and Oracle JDK). It is hard to fix in a correct manner without trading significant performance. Marking dupe of original. *** This bug has been marked as a duplicate of bug 560232 *** There's: changeset: 2354:ee385b4e2ffb user: sherman date: Thu Mar 11 14:06:09 2010 -0800 summary: 6929479: Add a system property sun.zip.disableMemoryMapping to disable mmap use in ZipFile I thought someone had backported this to 6 but I don't see it. |
