I’m using version 8.4.0.3402. I’m running the servoy application server on an AWS server. I recently uploaded a patch from Servoy that fixed an issue where stored procedures weren’t being called. Since then whenever I upload a smart client solution into the application server it usually takes 2-3 hours for the solution to finish uploading. Sometimes it fails, which is extremely frustrating since I have to start the upload again and check in on it every couple hours to make sure it succeeds. Has anyone else experienced long upload times like this before? ---

Hi Ryan, Are you able to generate a **stack dump** while you are waiting for it to upload ? Best, Sean ---

Yes, I’m deploying this weekend, so I’ll generate one on Friday and send it to you then. ---

Hi Ryan, In this stack, the app server is waiting on the repository database. It would be helpful if you could capture a few stack dumps several seconds apart. For example, the next time that you experience the slow import, capture 5 stack dumps about 10 seconds apart, then we get a continuous picture of what is happening. Also, I wonder if you have tried on a clean/new repository database ? Could be that there are many versions and the queries are slowing ? I also wonder if you have any network trouble. Does it only happen occasionally? Or every time? ---

I’m going to email these to you since they’re so large. ---

One thought: is version is 8.4.0.3402 the one which was spawning too many threads? There was a bug which reported a while ago and was fixed by Servoy in one of the 8.4.x releases. Importing was fine for me, but in use my server would grind to a halt spawning too many threads. ---

Sorry, my problem was with 8.2.1… ---

Hi Ryan, Servoy R&D has analyzed your stack dumps and we see that the import process is really just hung waiting for something in SQLServer (presumably the repository db) But if it’s not really doing anything, then something in the DB may be locked. I recommend that you pick your DB admin tool and analyze it from there. Also, another option might be to do a full war deployment (instead of .servoy) which is lighter on the repository db (just column information is loaded). Maybe this would help.
