Since the kernel 2.6.12 (at least every 2.6.12 from Fedora Core 3) , I'm unable to generate useful core dumps with gcore. I always have the following messages : warning: The current VSYSCALL page code requires an existing execuitable. Use "add-symbol-file-from-memory" to load the VSYSCALL page by hand Then ,indeed, there no more symbols included in my core files, which makes them useless. Is this a security issue ? (selinux is disabled) , a gdb one ? (gdb hasn't been updated since quite a long time ) Does someone know if there's an issue for that (a lot of my admin scripts rely on gcore so this is really annoying) I havn't this problem with 2.6.11 kernels but 2.6.12 solved a lot of other bugs so I'd rather use it. Thanks. -- Cordialement / Cheers. -Olivier CNS
