Depending on your memtable thresholds the heap may be too small for the deployment. At the same time I don't see any other log statements around that long pause that you have shown in the log snippet. It looks little odd to me. All the ParNew collected almost same amount of heap and did not take lot of time.
Check if it is due to some JVM bug. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6477891 -Naren On Thu, Mar 17, 2011 at 9:47 AM, ruslan usifov <ruslan.usi...@gmail.com>wrote: > > > 2011/3/17 Narendra Sharma <narendra.sha...@gmail.com> > >> What heap size are you running with? and Which version of Cassandra? >> >> 4G with cassandra 0.7.4 >
