cannot create more threads.

[dragonii]

Hi

In the program, I want to run 200 threads concurrently, but in the client side, after create about 50 threads, it cannot create more, and print out the following messages:

08/19/10 07:07:41.202 ./ThreadClient: error: fatal error: can't accept more connections:
Network.cpp:1273: Ice::SocketException:
socket exception: Too many open files
0.0.0.0:33079
Aborted

I don't have any file operations in the program.

I'm using CentOS 4.8
Ice 3.3.1

Before running the Client, I set

ulimit -s 4096

Now I really don't know how to handle this problem, thanks for giving any help

Did you open too many files or net connection ? Check your code carefully, it seems some opend file or connection does't be closed.

No file operations in my code, and only one connection in one thread.


Thanks

Hi Rains,

I don't really understand what you're doing. And you should upgrade to Ice 3.4!

Is your ThreadClient really a server that creates lots of object adapters (one per thread??) Doesn't sound right.

Before running the Client, I set

ulimit -s 4096

ulimit -s sets the stack size. How is this relevant here? ulimit -n and ulimit -u would be more interesting here.

Best regards,
