The nodes still under heavy pressure and they dies after a random timeout (sometimes after 10 minutes of insertion and sometimes after 50 minutes).

I'm now on the RC1, I have n= o longer the ActiveCount error, however my nodes still dying under bulk ins= ertion.

I have modified my nodes configuration (al= l of them has now 2GB Heap size). The nodes still under heavy pressure and = they dies after a random timeout (sometimes after 10 minutes of insertion
and sometimes after 50 minutes).
I want to point that I'= m inserting rows in 4 different columns families at the same time and that = the rows size is too little (few KiloBytes).
I've attached he= re my cassandra.yaml configuration file.
Can you help me please to solve this issue?

Running nodes with different JVM heap sizes would not be recommen= ded practice, for many reasons. Nor would I recommend running them with all= the memory the machine has, it will just lead to the OS swapping the JVM o= ut to disk and considerable slow things down.

I would suggest a heap size of 1.5 or 2.0 GB for each n= ode, and have a read of the JVM Heap Size section here=A0http://wiki= .apache.org/cassandra/MemtableThresholds=A0. AFAIK the logs are showing= your cluster was under heavy GC pressure.=A0

Finally, the ActiveCount error message was a= known issue in beta 2. Treat yourself and try RC1 :)

by inserting 1 million rows (my target is to have 1billion rows) .
I have three nodes cluster (I'm using the same machines with 3GB of RA= M
each , intel core2 duo 1,6GHZ), RF =3D 2, CL =3D 1, HEAPSIZE of the seed = =3D 3GO
(it was 1.5GO, I've doubled it to avoid the heap size exception I had) = , the
other two nodes are 1.5GO.

I am using cassandra (V0.7.0-beta2) and Hector (V0.7.0.18) . I'm making=
insertion in batch mode using hector Mutator.
My disk_access_mode is standard.
I reduced also my memtable_throughput_in_mb to 64, but the problem persists=
and I have the following exception :
I want to know if it is a configuration or hardware problem ?
