Im using fiddler every where V2.2.0, and this problem has been quite a while.

It's normal when i capturing data such as html/json/text(or it just too small to be noticed), but when it comes to image/video, fiddler every where will use up all memory very quickly, even if i didn't capture that huge amount of data. And there is no way avoid this, setting rules or click remove all doesn't help, the only solution is restart fiddler, which is annoying because in nearly 99% memory used, it's no possiable to do anything unless you want to wait several minutes for a simple file save location selecte window to pop up.

I've tried using the Rules(Do not capture/Graceful close/ Non graceful close), and it doesn't help.

Here's a screenshot when i capture tiktok's video info, taffic useage is only 50MB~, and data includes video/image/protobuf/json/html. With a time passed by, and some anaylize of thoes text body(no image nor video body), memory use 32GB.

What the h?

Hello Michael,

 

Thank you for reporting the issue and for providing the details. It looks like a legit problem when Fiddler Everywhere is running for a more extended period (in your case, the log indicates that time was more than 22 hours), so we will try to reproduce it on our side and implement better memory management.
Meanwhile, you could try the latest version that we have just released (version 3.0.0), where some of the UI optimizations are already released (alongside new features like HTTP/2 support and WebSocket support).

 

Regards,

Thanks for replying, though it has running for a long period, but it doesn't caputure more data 

I just keep it in the backgound so when i need to use it, it will be ready rather than waiting for login(slow international connection due to Chinese GFW)

it keeps a low and steady memory useage when sleeping in the background, but after a small amount of video/image data captured(even like under 100MB), and some normal anaylazing of plain text data(json/protobuf/html), memory usage will grow huge.

I've upgraded to 3.0 immediately yesterday when Fiddler Everywhere push the notification, and i will keep looking for any progress of this question or any other potential problem.
