I run a powerful anti-spam milter on my BlueOnyx servers called j-chkmail.
It's run fine for years across many versions of j-chkmail and BlueOnyx and
BlueQuartz.
For the first time last week I compiled and installed jchkmail-2.3.2 on a 5108R server
and it's doing periodic crashes. The same version compiles and runs fine on
a 5107R server.
I posted the crash output which appears on my screen to the j-chkmail mail
list, and the devs think there is a problem with 64bit libmilter. So I thought I
had better mention it here.
# ldd j-chkmail

Here is a copy of the crash output that peridically appears on my console.
