Bridge keeps regenerating cached thumbnails

Report · Apr 19, 2024

The later versions of Bridge keeps regenerating thumbnails every time the Bridge app window gets into focus. It has been like this for a while (used to be OK, not quite sure when this error was introduced). I have been hoping this would be fixed, but no luck so far.

Here is a repeatable sequence that will show this problem:

1) Select a smart collection in Bridge (workspace Filmstrip used)

In my case the collection targets a folder with 13 sub-folders (looking for files with one or more stars) holding the following file types:

.acr: 6 files

.CR2: 6274 files

.dng: 400 files

.psd: 2415 files

.xmp: 6274 files

TOTAL: 15369 files

2) Wait until things stabilize (no more activity generated by Bridge)

3) Place any (other) program window on top of the Bridge window

4) Observe that Bridge is still quiet

5) Remove (like minimize) the window now on top so that the Bridge window is fully exposed

6) Observe that Bridge now restarts generating thumbnails

7) The generation goes on for a while and consumes considerable (computer) resources (slows any other operations down)

8) When Bridge has finished, repeat: thumbnails are generated again ...

My workflow involves going back between Bridge and Photoshop. While Bridge is working (again) on the thumbnails, my machine gets quite busy, saturating all 16 cores and 32 threads (100% CPU utilization), and it gets somewhat laggy. This happens of course quite frequently.

The Bridge cache is located on my fastest disk, CORSAIR SSD Force MP600 Gen4 PCIex4 NVMe M.2. All the files mentioned are located on my SAMSUNG SSD MZ7L33T8HBNA-00A07 SATA disk.

It is worth noting that it seems to be only the thumbnails for the .CR2 raw files (from Canon EOS 5D Mark III) that are being regenerated. See the linked screen recording for details:

Before running the tests described above I did the following:

1) Deleted the Bridge cache (Bridge then automatically builds a new empty cache when started).

2) Cleared Bridge preferences (Ctrl+Alt+Shift on startup)

3) Uninstall Bridge

4) Install the latest version of Bridge (14.0.4.222)

Hey jjohanson. Thanks for sharing the details. We're sorry for the trouble. I'll help you figure this out.

We have released a new version of Bridge 14.1. To update Bridge to 14.1, click "Update" in the Creative Cloud desktop app next to Bridge. More detailed instructions for updating

You may need to update the Creative Cloud application and restart your computer to see the updated installer.

After updating the Bridge, if the issue persists, try the below steps:

1. In the preferences panel under cache->increase the cache size to max.

2. Check the purge cache that is older than n days. Increase the n value.

3. Automatically Export Cache to a folder when possible.

Please check this Community thread, which has a similar issue that you shared: https://community.adobe.com/t5/bridge-discussions/bridge-2018-re-caching-all-thumbnails-again/td-p/9...

Let me know if this helps,

Thanks!

Hello Shivani!

Thanks for the feedback!

Here are some further inputs:

1) I have been using Bridge version 14.1.0.257 for a while now. It still has the problem described above.

2) I have increased the Cache size to max, the new value is now 744 GB (before it was set to 360 GB). The actual used size of my cache (located at C:\Users\xxxxx\AppData\Roaming\Adobe\Bridge\Cache\v36 is currently around 86.7 GB.

3) I have set the Purge Cache Older Than value to 180 days (the maximum value allowed).

4) I can not find a setting anywhere named "Automatically Export Cache to a folder" anywhere in my Preferences ?? (see attached "Cache" and "Cache Management" settings.).

With the new settings/preferences above I see no difference in the behavior of Bridge:

Bridge keeps regenerating cached thumbnails whenever the Bridge window gets focus (using the same smart collection as described above for testing).

I have looked at the thread you refer to. It mentions "dancing XMPs" and "Re-caching when Camera Raw is updated". Not sure if this is related to the same bug (seems however that Camera Raw is involved in both cases). Note that I am experiencing recreation of cached thumbnails without any software update between each regeneration (just the Bridge window going in and out of focus).

One additional piece of info:

In addition to regenerating cached thumbnails every time the Bridge window gets focus, Bridge also regenerates cached thumbnails every time I selects/start the smart collection.

Regards

jjohanson
