I'm playing with an RPI3 running -current at r349989 and trying to build a port (firefox) with the ports tree at (....long delay to svnlite info command.....) 506825 using portmaster under the portmaster-devel script. The system is still running and mostly idle, as reported by top: last pid: 8739; load averages: 0.00, 0.02, 0.00 up 1+12:03:29 20:29:20 36 processes: 1 running, 35 sleeping CPU: 0.0% user, 0.0% nice, 0.1% system, 0.1% interrupt, 99.8% idle Mem: 22M Active, 720M Inact, 2324K Laundry, 137M Wired, 57M Buf, 27M Free Swap: 6349M Total, 23M Used, 6326M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAN 8374 root 1 26 0 27M 9160K biord 1 1:21 0.00% bsdtar 8739 root 1 21 0 21M 8108K sbwait 3 0:00 0.00% sshd 21314 bob 1 20 0 14M 1120K CPU2 2 3:44 0.20% top 21512 bob 1 21 0 13M 1108K ttyin 1 0:00 0.00% tcsh 970 root 1 20 0 16M 848K select 0 0:09 0.02% sendma 957 root 1 21 0 20M 688K select 0 0:05 0.00% sshd 38012 root 1 52 0 15M 656K wait 2 0:58 0.00% bash 973 smmsp 1 20 0 16M 548K pause 3 0:00 0.00% sendma 2036 bob 1 20 0 22M 544K select 1 0:22 0.02% sshd 977 root 1 20 0 12M 412K nanslp 0 0:03 0.00% cron 21511 bob 1 20 0 22M 408K select 0 0:00 0.00% sshd 826 root 1 20 0 11M 404K select 3 0:03 0.00% syslog 2001 bob 1 20 0 22M 244K select 1 0:04 0.00% sshd 2007 root 1 20 0 14M 140K pause 2 0:00 0.00% csh Every once in a while bsdtar will use a fraction of a percent of cpu, but that seems to be all that's happening. The timestamp updates every other second, typing echoes as expected but something like pwd takes twenty seconds to answer. The controlling terminal for portmaster-devel has been sitting at => SHA256 Checksum OK for rust/2019-05-23/cargo-0.36.0-aarch64-unknown-freebsd.tar.gz. for about two hours. There are sporadic reports of swap_pager: indefinite wait buffer: bufobj: 0, blkno: 516, size: 4096 on the console, but they're sparse. At least according to top there's no significant swap usage. This behavior isn't entirely new, but this is the first time it's been bad enough to seem worth reporting. The filesystem is 74% full, so it's not out of storage: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ufs/rootfs 116766684 78989800 28435552 74% / devfs 1 1 0 100% /dev /dev/msdosfs/MSDOSBOOT 51096 13552 37544 27% /boot/msdos Meanwhile an RPI2 running 11.3-BETA1 #0 r348441 is happily grinding away on the same problem with ports at 506786. It answered svnlite info /usr/ports in less than a second. Thanks for reading, and any thoughts. bob prohaska
