Kernel (+ xargs, IMHO) bug. Can be worked around by, e.g.:

       echo 128 > /proc/sys/kernel/audit_argv_kb

See <https://bugzilla.redhat.com/show_bug.cgi?id=275321>

This "fixes" xargs (and others) going south with long ARGV.

In any case, AFAIU xargs(1) should negotiate/ask for the size of ARGV, and
doing it wrong. I.e.:

  $ xargs --show-limits
  Your environment variables take up 2509 bytes
  POSIX lower and upper limits on argument length: 2048, 129024
  Maximum length of command we could actually use: 126515
  Size of command buffer we are actually using: 126515
