Should be good, but its possible the path to tar is hardcoded into
amanda, mine is, and all I have to do is change that path, recompile
and reinstall and I'm back on the older 1.13-25. I took advantage of
that when I thought I'd see if the lastest tar-1.15-1 worked with
amanda, and it does. So if you kept a copy of the configuration
driver script (doesn't everybody?), you might want to see if it
points at the same tar as a 'which tar' does.

Yes. It may also indicate a drive cableing problem, but after
verifying they're all plugged in solidly, I think I'd reboot on a
recent cd of linux and run the memtest86 utility, say for about 24
hours, unless you get a definitive bad memory output before that
time. That util is also available as a downloadable floppy image
thats self booting once dd'd to the floppy. If memtest86 comes up
with a clean bill of health, next would be drive cabling, tested by
replacement with fresh ones.
Another problem might be cpu cooling. If the grease under the
heatsink and fan has been there more than a year, its more than
likely you could cool the cpu off by 10-30 degress F, just by pulling
the cooler back off, blowing that 2 oz of dust bunnies out of it,
cleaning off the bottom of it and the top of the cpu, and replaceing
the grease with the appropriate stuff, some white silicone heat sink
compound, or in real coffee boiler 2ghz and up cpu's, a dab of 'Artic
Silver' which is 95% silver ground up micron fine, with a bit of
silicone grease to make a putty like substance out of it, and which
if properly done, can cut the degrees per watt differential between
the top pf the cpu and the bottom of the heat sink by half or more.
It doesn't take very much, half a matchhead evenly spread should do
it just fine since that roughly 1cm sq area on the top of the cpu is
all that needs it.
The reason I note that is that allthough I'm running setiathome here,
which keeps the cpu running at 100%, when gzip -best is running, the
temps go up another degree or 2. Zalman Flower cooler here, and my
grease is drying out, its up about 13 degress since it was installed
last summer. But I usually practice what I preach as all this stuff
goes out on the front porch to be cleaned out with an air compressor
and the heat sinks regreased every spring. Currently showing 138-140
degrees in gkrellm.
