https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255499 --- Comment #8 from teodorsigaev@gmail.com <teodorsigaev@gmail.com> --- Hello! I faced with freezing my desktop. When I compiled new postgres and run test= s by 'gmake -j8 check-world' that tests never finished and box after several min= utes become unresponsive if current application touches disk. Even Ctrl+Alt+Backspace after Xorg exiting doesn't return me to console command prompt. At this moment, systat shows writes to disk with 1.7Gb per second, although after rebooting I don't see any unexpected files, postgresql direc= tory takes only 4Gb spaces.=20 Also, removing ports tree causes very close sympthoms, although after 10 minutes after rm finished OS came back to work. So, after rm finished, I see 1.7Gb writes per second on disks. I made several tries to resolve: - I noticed, that root terminal lives longer than terminals of unprivileg= ed=20 user and found that only root has unlimited memorylocked limit. Changing this limit - no success. - Tried on/off IOMMU option in kerconf. No luck. - increase .sujournal - again - Update firmware on NVMe driver - the same - Suggested that somehow old data on disk wasn't trimmed (TRIM/BIO_DELETE command) and I wrote ~1.5 Tb file and erased it in hope that system wil= l=20 send trim command to drive. No result. Note, Freebsd 12.2 worked well even with -j16 parallelization. And my second box, laptop with Freebsd 13, works well with the same args. Pls, help me to resolve issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
