Thousands of Socket in state TIME_WAIT after startup

[former_member956918]

Hello,

we're facing the problem, that our Solution Manager 7.1 assignes thousands of sockets in windows 2008 r2:

  TCP    127.0.0.1:49246        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49247        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49248        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49249        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49250        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49251        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49252        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49253        HOSTNAME:sapgw01      TIME_WAIT

  TCP    127.0.0.1:49254        HOSTNAME:sapgw01      TIME_WAIT

......

Kernel version is 7.20 uc amd64 pl 500

I can't find something about this error in the OSS.

best regards

Maybe these notes could help you:

1410736 - TCP/IP: setting keepalive interval 

743888 - GW: gw/so_keepalive profile parameter

sorry this not the solution.

forgot to tell, that all these are connection to Localhost. So a bridge/router/switch is not affected.

The problem only occurs, when server0 is started on SolMan..

In the traces is see many error. about 1000 per second:

Hello

Have you checked the gateway trace file ?

It looks like this is caused by the SMD and/or Wily Introscope.

I Also see this in the tracefile about 1000 times second:

the Problem was caused by a wrong configuration of reginfo und secinfo.

But i'm wondering why the RFC retry-speed between java and abap is that fast, that all OS-Sockets will be in use..
