MIME::Parser: can't open tmpfile: Invalid argument

[Joe Eckard]

I have been using MailScanner for quite some time now, and I have to
say that it has been working great. However, I recently brought a new
mail server online and attempted to install the latest version - I am
getting errors that I can't seem to resolve. Has anyone else seen
these, or is it obvious what is wrong? I am running FreeBSD 5.0, Perl
5.8.0, sendmail 8.12.8 and the recommended versions of all required
perl modules. (My working copy was MS 3.20 on FreeBSD 4.1 with sendmail
8.12.8)

here is the maillog output:

Any advice would be greatly appreciated...

Thanks,

Joe

sidenote: on my old system, mailscanner always ran as a single
process... however now it starts out as 2, and the number of instances
steadily increases until I kill them all off.
