In order to update to the latest stable PyQt5-5.13.2 , I was required to remerge qtwebkit-5.212.0_pre20190629 ; this normally takes 30 min & can make its cache in memory.
Towards the end of the latter compile, I suddenly found myself looking at a completely dark screen : the whole system had crashed. I pressed the Start button on the box & tried the emerge again, watching what was going on during the compile, while monitoring 'free' on another tab & activity on Gkrellm. Early in the compile, it briefly used most of swap : I have 8 GB memory + 8 GB swap partition & it was using c 4,5 GB swap ; this dropped again fairly quickly. All 8 processors were running at 100 % or nearly & the CPU temperature was 70 C with fans whining a bit. Then at the same point in the compile, poof ! -- another hard crash. Nothing at all in 'syslog' ; 'kern.log' shows : Jan 4 13:23:56 localhost kernel: IPv6: ADDRCONF(NETDEV_CHANGE): enp2s0: link becomes ready Jan 4 14:09:33 localhost kernel: Kernel logging (proc) stopped. Jan 4 14:09:33 localhost kernel: Kernel log daemon terminating. < this wb the crash, then restart > Jan 4 14:09:55 localhost kernel: klogd 1.5.1, log source = /proc/kmsg started. Jan 4 14:09:55 localhost kernel: Inspecting /usr/src/linux/System.map Jan 4 14:09:55 localhost kernel: Cannot find map file. Jan 4 14:09:55 localhost kernel: Loaded 30475 symbols from 1 module. Jan 4 14:09:55 localhost kernel: Linux version 4.14.52-gentoo (root@localhost) (gcc version 7.3.0 (Gentoo 7.3.0-r3 p1.4)) #5 SMP Sun Aug 19 23:59:47 EDT 201 which isn't very helpful. What evidence there was suggested that it had run out of swap, causing the kernel to panic, so I added 'dev-qt/qtwebkit notmpfs.conf' to /etc/portage/package.env , tried the emerge again & it went thro' successfully in 29 min . If you try to emerge LO or FF using a tmpfs , Portage tells you not to. Rust is the 4th entry in package.env : I forget whether Portage/other warned me or I found out the hard way. It's also a puzzle why qtwebkit failed on this re-merge after compiling successfully when previously updated a few months ago. It's a very long time since my system (on any box) crashed in this manner. This is FYI, but others might have a few comments. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
