Unix Password Sync Problem

[Todd Stiers]

Hmm,

Well, I recompiled with all the patches applied (after a make clean too!)
and I still get the same PANIC on segfault.

[1999/05/13 10:18:48, 3] smbd/chgpasswd.c:chgpasswd(385)
  Password change for user: herman
[1999/05/13 10:18:48, 0] lib/fault.c:fault_report(40)
  ===============================================================
[1999/05/13 10:18:48, 0] lib/fault.c:fault_report(41)
  INTERNAL ERROR: Signal 11 in pid 19357 (2.1.0-prealpha)
  Please read the file BUGS.txt in the distribution

  ===============================================================
[1999/05/13 10:18:48, 0] lib/util.c:smb_panic(2538)
  PANIC: internal error
  do_reseed: got 40 bytes from /dev/random.
[1999/05/13 10:18:48, 5] locking/shmem.c:smb_shm_open(819)

Thanks though,
