java.net.SocketException

Bonjour everybody

I use Jmeter for my tests (send https requests to a web server)
I use a linux PC with 512Mo of memory.
My test plan is simple :
  Thread group with 400 threads with a Ram-up of 300 seconds and just 1 loop.
     Request defaults
     Cookie manager
     Page request (https)
     File reporter


after launching all the thread, i have some request response Ok 
but for some threads (about 200), I have this exception :
java.net.SocketException: Unexpected end of file from server

        at java.lang.Thread.run(Unknown Source)

the max use of the CPU is  30%.
Can you help me, please ?

It sounds like your server might be rejecting some of the threads?  To test this, try adding 
a Timer to your test and create a delay between samples. If this decreases the number of 
errors you see, it's a good indication that your server is being overwhelmed.
