我正在为Apache（v2.4）使用weblogic代理插件（12c）。一段时间后，Apache日志会出现以下错误：
[Mon Jun 27 13:01:09.570646 2016] [weblogic:error] [pid 18224] [client 192.135.176.51:60667] ap_proxy: trying GET /websocket/hcsnotifications/jSocket at backend host ; got exception 'NO_RESOURCES: [os error=115, line 2859 of ApacheProxy.cpp]: Active Websocket Connection Limit Reached'; state: preparing request headers (wrote?

以下是我的httpd.conf：
ServerTokens OS
ServerRoot "/etc/httpd"
PidFile run/httpd.pid
Timeout 295
KeepAlive Off
MaxKeepAliveRequests 100
KeepAliveTimeout 15
WLMaxWebSocketClients 1024
# prefork MPM
<IfModule prefork.c>
StartServers 25
MinSpareServers 50
MaxSpareServers 200
ServerLimit 2048
MaxClients 2048
MaxRequestsPerChild 2000
#WLMaxWebSocketClients 1024
</IfModule>
因此，按照上面的配置，我将WebSocket连接限制设置为1024，但它达到了30-40个连接的限制。
