QC GUI is down


(Zhaozhong Shi) #1

It looks like the QC GUI is currently down https://qcg-test.cern.ch

I get an error of 504 Gateway Time-out. Can anyone fix it quickly? Thank you very much

I have restarted it.
@awegrzyn you might want to have a look. Or maybe George ?


(Adam Wegrzynek) #3

Done ! I need to investigate what happened, there were no logs indicating any failure.


(Zhaozhong Shi) #4

Down again!!! @awegrzyn


(Adam Wegrzynek) #5

Not sure why it’s failing, it hasn’t been changed for weeks. I’m spying the logs now.

Hi @awegrzyn

It looks like when I add more plots t my layouts, it goes down. I think there maybe some problem when I do this? Thank you very much!

Hi,
So the error I get is: “fatal error: malformed or corrupted AST file: 'submodule ID out of range in AST file”. I suspect it may come from ROOT.
Anyway the process should not die because of that, I’ll add a protection.

@awegrzyn It look like the GUI is still down when I click on one of my layouts. Can you check again why this happens? It also looks like that when I exit the GUI and reenter twice, it will be back up. This seems quite strange to me.


(Zhaozhong Shi) #9

Can you restart the GUI? Sorry!


(Adam Wegrzynek) #10

Could you explain me at which point it dies? I can’t reproduce it.


(Zhaozhong Shi) #11

When I click on my layouts it dies. I guess the size of my plots are too large (~100MB each for ~30 plots). Can you restart the GUI again? Thank you! @awegrzyn


(Adam Wegrzynek) #12

Okay, I’ll try to fix it this afternoon. In general systemd should restart the process after a while by itself.


(Zhaozhong Shi) #13

Thanks so much

Hi @awegrzyn, I started my own GUI. When I add more than 5 plots of size 80KB, I got the following error messages:

*** Error in node': free(): invalid pointer: 0x00007fe49bdaecc8 *** *** Error innode’: corrupted size vs. prev_size: 0x00007fe47803a260 ***

*** Break *** segmentation violation

*** Break *** segmentation violation

*** Break *** segmentation violation

Do you know what is going on? Thank you very much!


(Adam Wegrzynek) #15

Yes, there’s already JIRA ticket created concerning that: OGUI-291


(Zhaozhong Shi) #16

Can you check why this happens? I have no idea why.


(Zhaozhong Shi) #17

Hi @awegrzyn, I found the bugs. So after 3 times of publishing my updated plots to a certain layout, the GUI is down. Do you know why this happens? Thank you!

Hi @szhaozho,

I know that you don’t mean to bother Adam, at the same time pushing him every hour is not going to make him work faster or motivate him further. Adam is very responsive and already working on this issue as he expressed above. This bug can be discussed in the bug report he opened here : https://alice.its.cern.ch/jira/browse/OGUI-291

Cheers,
Barth

Hi @bvonhall ,

Sorry about that. I think I have sent too many messages to push him all the time.

Sincerely,
Zhaozhong Shi
