JMeter Ubuntu: java.net.SocketException: Too many open files

Once JMeter script with 5000 values in CSV file is executed with Synchronization Timer, Response data in View Results in Tree shows following error:

java.net.SocketException: Too many open files

I could not find the satisfactory answer yet on google.

Is there any way to resolve this?

Increase the number of open file handles or file descriptors per process.

You can use command ulimit -a to find out how many open file handles per process is allowed.

$ ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
open files                    (-n) 1024
pipe size          (512 bytes, -p) 10
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 2048
virtual memory        (kbytes, -v) unlimited

You can see that, open files (-n) 1024, which means only 1024 open file handles per process is allowed. If your Java program exceeds this limit, it will throw java.net.SocketException: Too many files open error.

See these threads I/O exception (java.net.SocketException) and java.net.SocketException: Too many open files.
