Subject java.io.IOException in cassandra 1.0.1
Date Mon, 07 Nov 2011 17:02:10 GMT
Hi,

 We are running a 8 node cassandra cluster. We do reads and writes
with CL QUORUM.  During our performance test last weekend we noticed
compaction pending stats started growing after 10 hrs of testing.
System log showed errors  during compaction. I am attaching the
system.log file.  Is this a known issue?

thanks
Ramesh
