Re: error='Cannot allocate memory' (errno=12)

I see your ulimit -a above, missed that. You should increase nofile ulimit. If you used JNA, you'd need to increase memlock too, but you probably aren't using JNA. 1024 nofile is default and far too small, try making that like 64K. Thread handles can count against file descriptors limits, simil

Re: error='Cannot allocate memory' (errno=12)

What's your ulimit -a output? Did you adjust nproc and nofile ulimits up? Do you have JNA installed? What about memlock ulimit and in sysctl.conf => kernel.shmmax? What's in cassandra.log? On Mon, May 11, 2015 at 7:24 AM, Rahul Bhardwaj < rahul.bhard...@indiamart.com> wrote: > Hi Robert, > > I

Re: error='Cannot allocate memory' (errno=12)

Well i havent used 2.1.x cassandra neither java 8 but any reason for not using oracle JDK as i thought thats what is recommended. i saw a thread earlier stating java 8 with 2.0.14+ cassandra is tested but not sure about 2.1.x versions. On Mon, May 11, 2015 at 4:04 PM, Rahul Bhardwaj < rahul.bhard

Re: error='Cannot allocate memory' (errno=12)

the memory cassandra is trying to allocate is pretty small. you sure there is no hardware failure on the machine. what is the free ram on the box ? On Mon, May 11, 2015 at 3:28 PM, Rahul Bhardwaj < rahul.bhard...@indiamart.com> wrote: > Hi All, > > We have cluster of 3 nodes with 64GB RAM each.
