Thanks for this heads-up. I've updated our short report.

BTW, in fssync and salvsync and a couple other places in the code we see:
    #define FD_SETSIZE 65536

Naive question=85 would an alternative "fix" here be to do something like:

#ifdef LINUX
    #define FD_SETSIZE 1024
#endif

then AFS would work independent of the ulimit, (at least until select() is =
removed everywhere)?

Cheers, Dan
