Too many open files error
-------------------------
Key: AXIS2-2581
URL: https://issues.apache.org/jira/browse/AXIS2-2581
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: client-api
Affects Versions: nightly
Environment: Linux version 2.6.15-26-amd64-k8, Java HotSpot(TM) 64-Bit
Server VM (build 1.5.0_08-b03, mixed mode)
Reporter: Michele Mazzucco
Priority: Critical
I'm running out of sockets after a few minutes. The same client works fine on
Mac OS X (JMX 1.5.0_07).
The client sends 2 requests type to the server(s):
- type 1: 0.2 requests/second. Service time 50 seconds (avg)
- type 2: 1.8 requets/seconds. Service time 5 seconds (avg).
After about 10 minutes the client crashes because the client machine runs out
of sockets (ulimit -n = 1024):
