           Summary: SpamdForkScaling - sysread errors
           Product: Spamassassin
           Version: 3.1.8
          Platform: Other
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P3
         Component: spamc/spamd
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: robert@devnull.us


FreeBSD:  4.11
PERL:  5.8.5
SpamAssassin: 3.1.8 (occured under 3.1.6 also)

Spamd launched with:
/usr/local/bin/spamd -x -q -i 0.0.0.0 -m 20 --min-spare=2 --max-spare=10 -d -u
spamd -d -r /var/run/spamd/spamd.pid (perl)


We have four spamd servers.  Occasionally we see this on a couple of them,
probably 5-6 times a day each.  Spamd seems to be ok when this happens, it seems
like only the child is effected and perhaps restarted?

It doesn't seem to occur at any specific time.  A couple of logs with the
prefork statuses below from two different servers:
