pyzor error TERMINATED signal 15

[Maxim K. <max...@gm...>]

I am getting this in the logs for each email being processed by Pyzor:

Tue Apr  6 11:22:57 2010 [60458] info: pyzor: [60795] error:
TERMINATED, signal 15 (000f)

Is that normal (and can be ignored) or something indicates Pyzor is
failing the checking?

SpamAssassin version 3.3.0 running on Perl version 5.8.9, FreeBSD 6.3
