Docker server not updating

[Thiago Falcão]

Hello. I've been using a docker server for some years now. It happens the server had to be shut for a while (some months) and after turning it on again (with no changes to network nor anything else) it is not working as it used anymore. Back then, the images used to be sent from the CR to server almost instantly and now images are taking so long and, sometimes, images are not sent to the server. I was looking into the wildfly log and I found something weird.

This is part of the log. It keep changing ports and not sending/receiving images. I don't know what is happening and how to troubleshoot it. I need some help here. Anyone?

I'm using the minimum set of archive services on a single host.

There is not any attempt from CLASSIC_EV to send any image. Increase level of Logging Category org.dcm4che3.net.Association to DEBUG, to see which Presentation Contexts are offered by CLASSIC_EV in the A-ASSOCIATE-RQ and which are accepted by DCM4CHEE in the returned A-ASSOCIATE-AC.

That sounds weird because if I go to CLASSIC_EV, there are images from a week ago in the queue to be sent to the server.

I'm trying to troubleshoot but I am really confused to what is happening.

Hey Thiago,

I don't know what might happening in your case, but here are some troubleshooting ideas:

- Do you have the LDAP server volumes monted to your host machine? In case you didn't mount, probably you lost your configuration data, in other words, If you did some manual configuration using UI in this meantime, probably you lost it.

- Maybe the other end is causing the issue. Try to send an simple Dicom file using dcmsend (from dcmtk or dcm4che tools) command from your machine and see if you get same results.

- Try to attach a sniffer to your network. TcpDump will help you with that. If you are using Windows, Wireshark is a good option.

I hope it helps!

[Thiago Falcão]

I'll look into it. Thanks.
