Caught signal: SIGSEGV (might be memory or disk space related)
Author: DobatymoCreated Sep 17, 2026Updated Sep 17, 2026
qBittorrent & operating system versions
qBittorrent version: v5.2.3 (64-bit) Libtorrent version: 1.2.20.0 Qt version: 6.10.3 Boost version: 1.86.0 OpenSSL version: 3.6.3 zlib version: 1.3.2 OS version: Windows 11 Version 25H2 10.0.26200 x86_64
What is the problem?
It crashed while just downloading/uploading in the background. I wasn't actively doing something with it. It might be related to low memory or disk space. I had a Firefox tab crash at the same time.
