We started seeing for the first time errors that look like this last night
after things were running smoothly for a couple days after switching to
0.6-rc1:
ERROR [pool-1-thread-60] 2010-04-13 04:58:11,806 Cassandra.java (line 1492)
Internal error processing insert
We had not made any other change
Nope it's always been random.

Right, that's what I meant, thanks for the correction.

Yep I believe those are inserts per second. Take the last line:
"811653,1666,250"
I believe that's telling you that during that 10 second interval you did
1666 inserts but your overall insert rate is 811653/250 = 3246.612
inserts/sec.
Timeouts may be due to your machine(s) being fully saturated?
I don't know if this is from switching from 0.5 to 0.6-betarc3 just recently
or from doing a series of bootstrap and removeToken operations but I
recently started getting ArrayIndexOutOfBoundsException exceptions (centered
around reading UTF from SSTableSliceIterator) on one of the machines in my
c
Not that this is much better, but can't you replace steps 1-2 with nodeprobe
-flush ?
