Not Responding

Post by vkfoto » 05 Jan 21 0:40

What could make PSU not respond?
I open the application and change to Folders
I click on the black triangle beside the path to the images to expand the view and everything freezes. Task Master shows 0% CPU and 0% Disk. The catalog is excluded from my anti-virus.In Explorer I can quickly see all of the folders and their images.-
How long should I wait?

Don't know if it's me but after forcing PSu to close and rebooting since there was a not Responding instance in memory (as per Resource monitor) that was not showing in Task Manager. Restarted PSu and this time i couldn't even go to the Folders before everything froze. 2021 is not starting very well as far as my DAM is concerned.
For what it's worth, these four are always left, even the 0 byte ones.

Leaving them or deleting them makes no difference to the freezing

Ah, I think it WAS me. While looking at my disks, I saw the photo drive (SSD) was getting full. All those back ups take up a lot of space. After deleting half of them, PSu started normally again.

note to self, make sure the PSu catalog has lots of free space.

Indeed, and you should never delete these SHM and WAL files. SQLite will handle those when it opens the database again. Deleting the SHM or WAL files may cause permanent corruption.

Well now my SSD drive has lots of room. I only tried to select a second image in the same folder in order to apply the same labels. I held down the Ctrl key and before I could select the second image PSU became not responding. Task Manager shows 0% CPU, Disk and Network activity for IDimagerSU. It is still using 301.1 MB of memory. It doesn't seem to matter how long I wait, it never comes back. If I close PSU, Resource Monitor reports there is still an IDimagerSU in suspended mode.The only way to close that is to reboot.

Kill the hanging process in Windows Task Manager and start PSU again. If you can reproduce this then please let me know

Sometime during the night it untangled itself and by morning memory usage had shot up to over 1000 MB. I was able to complete that action I started before it became not responding. Then closed and restarted PSU, just to start fresh. Is that a lot for only 641 images? It's a new database for scanned photos that will eventually be integrated into the main photo database.

It still happens on an irregular basis. After updating dozens of images with extra labels, I add a location to a one more image, PSU became not responding and memory usage has shot up to over 1800 MB. There are only just over 2000 images in this catalog.
Is there some log file that can track each action to know what leads up to these situations?

After successfully Compacting the small database (1828 images) I started a backup. The Information box at the end says Catalog backup finished and PSU is not responding.

After about 30 minutes it is responding again. :?

Again after a compact and a backup, both successful this time, I clicked on a few random images thumbnails to get a bigger view. After clicking on the second image, PSU froze.

And again, after about 30 minutes it unfroze.

I'm now at version 3625 and still get the not responding issue.
I searched for missing folders and files at the top level and found 205 new files. All seemed to work fine until the Building Thumbnails started. It got to 80.9% and has been stuck there for over half an hour. Other programs can see and display all the files around the one it is stuck on (if the file name shown in the Building Thumbnails is the one where it stopped). Can't click on the X beside the progress bar the Building area, the screen just becomes pale.

It was only 205 images, how small a set does it have to be to not choke?

After 45 minutes it woke up and continued. What happened?

I import a test set of 20k images at least once a week and never get stalls. Psu 6 is rock solid. You probably have some files in this set that kill psu.

Since it’s only 200 files, it should be very easy for you to find the culprit. Build thumbs for the first half, the the second half, and repeat dividing the set until you find the one

Well I sliced and diced but rebuilding the thumbnails worked just fine. I suppose the rebuild is exactly the same process as the first building of the thumbnails. It would seem that the thumbnail stall was just a casualty of something else that was causing the not responding. As a further test, I deleted the files, compacted the database and thumbnails and searched again for any missing folders and files. ... and nothing bad happened.
A one-off glitch?
