clientProjExt bug when update patch

[pablo.chamorro]

Hello everyone,

We have a weird client proj directory since we update our winccoa servers patch.

We use the webClient entry clientProjExt = 1, to difference our differents servers in the client side but, since we update the server patch, our clients are using a single directory with the name: projectName_-1

We update our winccoa 3.17P12 servers to 3.17P30, maybe this is a known behaivor and we are missing something?

I did a test with WinCC OA 3.17 and I get an error when using the config entry clientProjExt = 1.

Can you please check if you get the same error in your project.
The error might be the cause why the project name is not correct.

I have fixed the bug which causes the log messages. The bugfix will be included in a future patch for WinCC OA 3.17.
Newer WinCC OA versions are not affected.

Hello again,

Could that bug also affect to the clients connection with the event manager? Since the update, we are experimenting also a randomly expired connection error when we try to open web or desktop client. Only restarting the winccoa server the clients are able to connect again.

This is the log messages, where the IP was modified.
