I had somehow lost the main database file. Once regenerated, program could once again test and update. Program should protect itself against missing or invalid data rather than proceed and segfault out.
I now get the following which I never got before: ### Warning: File system error. ### Filename: /proc/mdstat ### No such file or directory ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/auth.domain/flush ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/auth.unix.ip/channel ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/auth.unix.ip/flush ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfs4.idtoname/channel ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfs4.idtoname/flush ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfs4.nametoid/channel ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfs4.nametoid/flush ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfsd.export/channel ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfsd.export/flush ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfsd.fh/channel ### Illegal seek ### Continuing... ### Warning: File could not be opened. ### Filename: /proc/net/rpc/nfsd.fh/flush ### Illegal seek ### Continuing... after which it works OK. So close orignal bug and open one about the segfault instead of graceful end with corrupt or missing database file. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
