This is on a Fedora 8 installation. The last four entries are from
a freshly installed 3.2.4; earlies ones from 3.2.3. So far nothing
from today and first samples I noticed are from January 14th. No
obvious candidates in other, possibly related, software changed on
that or close preceding date.
In mail logs I see a corresponding lines like these:
... spamd[9396]: spamd: processing message <[EMAIL PROTECTED]> for ...
... spamd[4671]: prefork: child states: BI
... spamd[4671]: spamd: handled cleanup of child pid 9396 due to SIGCHLD
... spamd[4671]: spamd: server successfully spawned child process, pid 11150
Segfaults are always in children forked to handle specific messages
so a general operation is not affected and a parent spamd continues
to run.
Looking closer through logs all these incidents happen with mail
to one account and on that account .procmailrc is present and nearly
all mail (there are some other, rare, cases) is handled like that:
:0:
* ^X-Spam-Flag:.*YES
/dev/null
:0
! [EMAIL PROTECTED]
That .procmailrc was not changed for over two years.
This is the only mail server on x86_64 which I can watch in such
detail and with a significant amount of mail traffic. I have another
server which handles even more mail, and it has spamassassin-3.2.4
in operation, but that one is on an i386 machine. I did not observe
anything of the similar sort there.
This was initially reported for 3.2.3 as
