Has anybody else experienced massive loss of images in the cache directory or is it 1and1.com messing up?

I have filled the cache, verified all images (small and thumb) are there and show in the browser, checked weekly, ...

Then I stop checking and all or most all of the cache is gone. This is the 4th time this has happened! This time all but about 18 of the small.jpg images are gone.

Needless to say I am frustrated.

Actually TWG does check the cache if files are not touched for a long time. But only .small.jpg and the slideshow images are checked.
No thumbnails.

$cache_time=42;

Is the settings where you can set / disable this behaviour. and 42 is the number of days.
But as I said. Thumbnails are never removed.

I don't know what 1and1 is doing here. how many images where in the cache?

set
$cache_time=-1;
Then this is disabled.

I just checked my cache folder of the demos where many version of TWG where deployed. The oldest files (thumbs) are more than 1 1/2 years old. My .small images are actually very new. But this depends on the server. If the file date when the file was at last accessed is not updated properly by the OS the file is regenerated.

I just checked the code.
I use fileatime which should return the time the file was accessed the last time.
But I read also that this is sometimes disabled in devices with lot of traffic. And 1and1 could have disabled this.
But you say that thumbs are gone as well. Therefore I think this is not your problem.

I added an additional check if the last accessed time is different to the last modified date. If they are equal I don't cleanup the cache because the last access time is most likely disabled like on your system.

I'll test this on my demo right now and this will be included in the final of 1.7.6.
