@RomanovskyAnd Greetings! In order to troubleshoot this issue, we need to get your application logs.

1. Go to Settings -> App settings -> Advanced settings -> Logging level -> Extended.
2. Reproduce the problem, remember the exact time it happened.
3. Create a .dmp file: Task manager - click RMB on memory consuming process - Create a dump file.
4. Open Settings -> App settings -> Advanced settings -> Export logs and system info.
5. Send the archive and .dmp file to qa@adguard.com:

• include [windows] keyword and 1183 in the subject of your email
• specify the exact time when the issue occurred.

Dump file has 7GB size at the beginning - I will upload it to Google Drive?
p.s. after zipping it I got 230mb file

@RomanovskyAnd Of course, You can just mention the google drive link in email.

@RomanovskyAnd Can You, please, specify - is there any antiviruses or other network software running on your PC?

Also, what about newest 2.9.6 version - high RAM consuption is the same with it?

@KolbasovAnton only built in Win software - nothing else
for 2.9.6 seems issue not reproduced any more
