LCDS/Flex/RTMP File Descriptor Leak STSO /dev/tcp->tcpm->ip

[nunoHyun]

Hello all,

   I have an application using Flex 3 and RTMP

RTMP exit (WebBrowser Close, refresh, the client exits (Consumer disconnect))

when the server will increase the number of file descriptors.

This is still piled up over time a problem occurs on the server.

Exception in thread

"RTMP-Server" flex.messaging.endpoints.rtmp.RTMPException: The RTMP server has encountered a fatal exception starting up: Too many open files (errno:24)

Server OS: HP unix 11.11
WAS: tomcat6.0
JDK: 1.5
LCDS: 2.5.1

* Rtmp port: 2040

Many such issues have been fixed since 2.5.1.   Can you try LCDS 3.1?

lcds 3.1 version, Does not work

lcds-samples test results of the trading desktop

lcds 3.1 version of the same symptoms, but seems to apply

hpux 11.11 shows that all versions of the same symptoms.

I wonder why this problem occurs...
