Subject: wu-ftpd-2.4 crashes x86 with Solaris?

Hi,

We've setup wu-ftpd-2.4 on a x86 (a 486 and a Pentium) running Solaris 2.4
for both anonymous and guest ftp users. Everything is running fine but
we've got two problems (so, not everything is running fine :-)):

- it sometimes crashes the system (BAD TRAP). We have no hard proof for it
  yet, but everytime the system crashes, the last two lines in the messages
  file are from ftpd logging USER and PASS:
    Oct 22 19:01:23 asterix ftpd[24450]: USER username
    Oct 22 19:01:24 asterix ftpd[24450]: PASS password
    Oct 22 19:04:30 asterix unix:  SunOS Release 5.4 Version Generic_101946-12 [UNIX(R) System V Release 4.0]
  This happens very (too) regularly, like twice a day, but not every time
  someone logs in with ftp.

- every now and then a ftpd keeps hanging around. Probably caused by
  persons not exiting their ftp-client in a clean way.  And after the
  maximum number of ftpd is reached, no user can login anymore.  Running
  'netstat -a' shows a lot of these entries:
            *.ftp       *.*                0      0  9648      0 BOUND
      obelix.32931      *.*                0      0     0      0 LISTEN
    [ obelix is the hostname ]
  Of what I understand the new version (2.4.2) should fix this?

The following patches are installed:
- 101946-12: jumbo patch for kernel
- 102008-01: vnode v_count is not maintained correctly
- 102287-01: /usr/lib/utmpd fix

Especially the first problem causes us a lot of problems.
Can anyone help us out? If you need more information about the
configuration please mail me.

Thanks,
