--- Comment #3 from Manvydas Šliamka <manwiu...@gmail.com> --- I'm really sorry for not replying sooner, but the defense of my Master's thesis is soon and I just do not have the time to experiment with KDevelop extensively. First of all - tabs. I usually have 6-8 tabs open. Sometimes more, sometimes less, but it does not seem to influence memory consumption all that much. Next, I ran KDevelop with heaptrack in terminal, using: heaptrack ./KDevelop.AppImage I'm attaching the results file. Unfortunately, I'm not sure if it's complete or not because I had to kill KDevelop. The moment I noticed the system slowing down, I hit the close button on the KDevelop window. It closed and the memory use stopped increasing. However, the kdevelop process remained alive, maxing out a single CPU core. I waited for around 20 minutes, hoping for it to finish, but it did not and I had to kill it. That's when heaptrack finished as well and produced the heaptrack.KDevelop.AppImage.5390.gz that I'm attaching. Admittedly, I forgot to do this: gdb --pid $(pidof kdevelop) ... (gdb) call KDevelop::DUChain::self()->storeToDisk() I'll do it once I have more free time on my hands. I've also noticed that the terminal that I used to start KDevelop was fillied with hundreds of these messages: kdevplatform.shell: Broken text-document: QUrl("file:///tmp/kdevelop_Pa3204.patch") Plenty of these messages were in the terminal as well: kdevelop.plugins.clang: Something went wrong during 'clang_codeCompleteAt' for file "ONE_OF_MY_CURRENTTLY_OPEN_PROJECT_FILES" libclang: crash detected in code completion -- You are receiving this mail because: You are watching all bug changes.
