tar error after index creation?

Hi folks,
Can someone help me understand what happened here?  One of my AMANDA
clients is a Solaris 8 box that happens to have a rather large partition
containing user mailboxes and shell accounts.  It accounts for about
half of all my nightly backup data, so I noticed this morning when
backups finished hours earlier than usual.  The partition is about 35
GB, with approximately half that amount changing on any given run.  This
morning's run called for a level-3, which from past runs would probably
have been about 16 GB.

It looks like tar got some sort of error right off the bat.  Here is the
last bit of the sendbackup debug for this partition:

sendbackup-gnutar: time 0.957: doing level 3 dump from date: 2004-03-08
13:49:34 GMT
sendbackup: time 0.965: spawning /usr/local/libexec/runtar in pipeline

sendbackup: time 57.283: 124: strange(?): gtar:

sendbackup: time 61.324: pid 8170 finish time Tue Mar  9 06:42:11 2004


This partition failed to back up-- nothing was left in the server's
holding disk and it was noted "failed" in the mail report.  What I don't
understand is if the "strange" error is related to the "signal 11"
error.  FYI, /usr/local/bin/tar is GNU tar 1.13.19 from the SunFreeware
"SMCtar" package.  The client is running amanda-2.4.4p1 built from
source.

I don't know if it's relevant, but my dumptype is "high-tar":
define dumptype high-tar {
    program "GNUTAR"
    comment "partitions dumped with tar"
    options no-compress, index, exclude-list "/etc/amanda/exclude.gtar"
    priority high
}

Any insight would be appreciated.
Thanks!
Eric
