Hi
In our tests with RIAK the Java HTTP Client is running out of file
descriptors (currently 1024).
The test runs with 64 threads.
Has this behavior been observed by anyone before?
Any insights would be helpful.
Can you let me know what platform you are running on, version of Java
and which version of the client you are using, please?
We are currently running on a Debain Sid machine with Java version
"1.6.0_22".
Do you have the RiakConfig.setMaxConnections set to 64, too (or just
your test ThreadPool)?
The test thread pool is set to 64 (each thread does a riak operation).
Thanks for the info. Are you running a 64bit JVM?
We are running a 64 bit JVM.
I'm wondering if you're sharing the same RiakClient between all threads
or if each thread creates a RiakClient?
Each thread has a RiakClient.
I'm also wondering what your RiakConfig.setMaxConnections setting is?
(And which client version you have?)
This is not set, can I know what is the behavior in this case.
The client I am using is 0.9.1
Is it possible to see the test code, maybe?
I will try to post some snippets by tomorrow.
Also, just to sanity check, are you running against a Riak node on the
same box?
The riak node was on the same box.
http://wiki.basho.com/Open-Files-Limit.html says
"Riak can consume a large number of open file handles during normal
operation."
Since your client and server are on the same machine, have you used lsof
to check how many FDs Java (vs Riak itself) has and what state they are
in, especially if any are hanging around after your test code has run?
I do not have the lsof count. I will post it as soon as I run into the
same situation again.
Sorry for the barrage of questions.
Thanks to you for looking into this.
