Re: 2.0.10 to 2.0.11 upgrade and immediate ParNew and CMS GC storm

2014-10-29 Thread Duncan Sands
Hi Peter, are you using the hsha RPC server type on this node? If you are, then it looks like rpc_max_threads threads will be allocated on startup in 2.0.11 while this wasn't the case before. This can exhaust your heap if the value of rpc_max_threads is too large (eg if you use the default).

That definitely appears to be the issue. Thanks for pointing that out! https://issues.apache.org/jira/browse/CASSANDRA-8116 It looks like 2.0.12 will check for the default and throw an exception (thanks Mike Adamson) and also includes a bit more text in the config file but I'm thinking that

Some ideas: 1) Put on DEBUG log on the joining node to see what is going on in details with the stream with 1500 files 2) Check the stream ID to see whether it's a new stream or an old one pending On Wed, Oct 29, 2014 at 2:21 AM, Maxime maxim...@gmail.com wrote: Doan, thanks for the tip, I

tuning concurrent_reads param

2014-10-29 Thread Jimmy Lin
Hi, looking at the docs, the default value for concurrent_reads is 32, which seems bit small to me (comparing to say http server)? because if my node is receiving slight traffic, any more than 32 concurrent read query will have to wait.(?) Recommend rule is, 16* number of drives. Would that be

2014-10-29 Thread Chris Lohfink
Theres a bit to it, sometimes it can use tweaking though. Its a good default for most systems so I wouldn't increase right off the bat. When using ssds or something with a lot of horsepower it could be higher though (ie i2.xlarge+ on ec2). If you monitor the number of active threads in read
