Description Juraj 2019-01-03 17:52:01 UTC

SUMMARY
When using Falkon over longer period of time the main falkon process accumulate huge amount of memory. In my case I keep it running for few days (using laptop sleep mode) and in my observations there appears to be no limit on how much memory it can accumulate. I close (restart) falkon when it ate ~3GB of RAM

STEPS TO REPRODUCE
1. Start Falkon
2. Browse the web over longer period of time, This include opening and closing relatively large number of tabs
3. Over time observe memory consumption of main falkon process

OBSERVED RESULT
Over time falkon process accumulate huge amount of memory without stopping

EXPECTED RESULT
Falkon should keep track of its memory and not leak it over the time.

For the devs using Visual C++ here is a hint that could help to solve this problem:

This extension https://www.deleaker.com helps A LOT to detect memory leaks, it could make things easier for yous.
