Talend Enterprise Data Integration Administration cent. unresponsive

[fvittini]

We started to experience some slowness on our Talend Enterprise Data Integration server. When you click on the Login button it takes between 30 to 40 seconds showing the "Login processing..." msg, after finally displaying the welcome screen.
The Windows server resources seems to be fine, as CPU and memory usage look normal and this is a small talend installation with only 3 users.
I checked the log file and the only thing i see there is this error string, which repeat every now and then:

Does anyone has an idea what could be causing Talend to turn unresponsive.?

Hi,
Is it normal for your network? Could you please open a ticket on Talend Support Portal so that we can schedule a webex and give you a remote assistance.
Best regards

Thanks Sabrina,
It wasn't normal on our network. It started happening a couple of days ago. I'll check with Talend support though.
Regards,
Francis.
