I think this can happen (after such a failure) when JFFS2 realizes that it needs to rebuild/recover the active nodes in the file system. This can require a scan of the entire file system, along with rewriting some nodes, etc. > NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. > Fast Floating Point Emulator V0.9 (c) Peter Teichmann. > > There are some symbolic links in the root file system.

You should probably ask on some appropriate Linux mailing list. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
