sometimes it works sometimes it doesent… I cant have this working like this

pinyazhin · April 18, 2023, 6:30am

Hello!

Could you clarify what Jmix version do you use? Do you face this problem in clear new application?

eparamo · April 18, 2023, 6:58am

Latest version… application is realively new… it happened on a blank screen with just the component

pinyazhin · April 18, 2023, 7:23am

Does application contain add-ons (e.g. rest)? I’ve tried to reproduce the problem using fileUpload:

<fileUpload id="fileUpload" showFileName="true" showClearButton="true"/>

files with 67KB and 12MB are uploaded successfully. If it is possible could you share demo project with the problem?

eparamo · April 18, 2023, 3:45pm

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<window xmlns="http://jmix.io/schema/ui/window"
        caption="msg://blankScreen.caption">
    <layout>
        <fileUpload id="uplFIle"/>
    </layout>
</window>

this doesent work. no rest no anything… been struggling with this since yesterday…
works intermittently…
failed on a 15kb file
worked on a 2 kb file
then worked on the 15kb file.

pinyazhin · April 19, 2023, 7:51am

What JDK do you use? Does it happen in all browsers?

eparamo · April 20, 2023, 9:47pm

coretto 11…
Today I have not exeperienced the problem…
Im very confused… the error complains about a time out on the tomcat. could it be a memory issue on my machine… this computer is acting strange. im suspecting its hardware… closing post for now… thank you for your responses.

eparamo · April 30, 2023, 2:24am

Had it fail on a demo presentation yesterday… any idea why this gets stuck? im just uploading a 200kb file.

Does it happen on localhost?
Any details about the network between the application server and the user browser?

eparamo · June 14, 2023, 3:17pm

Its my local work machine. I create a new project. I put the upload component. I run my application in localhost and it does not work. I get this error. It sometimes works but 80% of the time its just stuck there and then time out error. the rest of the application works correctly

krivopustov · June 15, 2023, 8:35am

Could you clone this project: GitHub - jmix-framework/jmix-onboarding: Example application created in Jmix Tutorial, run it and try to upload an image in the user editor.

eparamo · June 15, 2023, 4:52pm

log.txt (13.5 KB)
I cloned it… and clicked RUN no changes what so ever.

I’m pretty sure if I leave this sitting here for 20 min and come back the file upload will work

I’m starting to believe its some kind of company network thing… uploading that log txt file took 2 tries…and was very slow…

eparamo · June 15, 2023, 6:26pm

left it here . retried after lunch break
and works as expected

krivopustov · June 16, 2023, 6:13am

Some antivirus/firewal/etc was checking what you tried to upload?

eparamo · June 17, 2023, 2:03am

I have no idea how to check for this. It just times out and works whenever it wants to

mbucan · June 19, 2023, 9:05am

Hello, here are few thoughts:

run diagnostic software on your hardware
try on another pc
use network diagnostic tools, experiment with 100 small files, and 10 large ones, monitor the statistic, especially look for periods with low transfer rate
experimenting with disabling certain features of your internet security software - sometimes it scans the file and finds false positives, and for good measure scan the files you transferred before but failed
are there any restrictions set to your pc, network infrastructure or servers that may throttle you down, or deny you because too many simultaneous users
is your Tomcat installed on some virtual machine?
and ofc check your resources - increase swap file size, memory allocated to server, and java opts
but the error doesn’t indicate out fo memory rather a network problem, you can also run a network test
if this happens intermittently, is there a cleaning lady with a vacuum cleaner near the network switch, or some device doing strong EM while working? - just asking, once upon a time entire country was losing its Internet access to the world exactly at 7:00 AM on Saturday …

I work from home using my company issued computer. so VPN and all enforced enterprise policies are in place. I create a new project, put an upload button… I click run… this error appears… I go for lunch leave this on… come back… and then it works… It has already happened in 2 presentations when I’m demoing this jmix application and have this fail on me. Its very concerning.
