Chances are you're temporarily out of space in /tmp during the run, but don't see it because the files are cleaned up on exit. I think you would be better off merging /tmp and /usr/tmp into a single slightly larger fs (or just use a partition on wd0 for tmp - alixes don't really have enough RAM to throw ~half of it into a ramdisk). Running under ktrace may give some clues. Try "ktrace -Bi pkg_add (...)". The file is likely to be large so maybe cd /usr/obj first, or use ktrace -f. Use kdump to see the plaintext version, which will be even larger, you might want to "kdump | gzip -1 > kdump.txt.gz" and copy it to another system to read it in an editor. Search backwards from the end of the file for part of the text in the error message, then work backwards. > Further information (cut-and-pasted from ssh session on the firewall): > > sodium# uname -a > OpenBSD sodium.bkis-orchard.net 6.5 GENERIC#1 i386 > sodium# df -hi > Filesystem Size Used Avail Capacity iused ifree %iused Mounted > on > /dev/wd0a 378M 47.7M 311M 13% 1771 47379 4% / > mfs:54350 62.9M 2.0M 57.7M 3% 8 8182 0% /tmp > /dev/wd0e 677M 15.1M 628M 2% 352 87710 0% /var > /dev/wd0f 1.5G 698M 734M 49% 16248 191622 8% /usr > mfs:42325 62.9M 2.0K 59.7M 0% 1 8189 0% /usr/tmp > /dev/wd0g 516M 138M 352M 28% 8980 58602 13% > /usr/X11R6 > /dev/wd0h 1.7G 218K 1.6G 0% 110 233744 0% > /usr/local > /dev/wd0j 5.1G 2.0K 4.8G 0% 1 701565 0% /usr/obj > /dev/wd0i 1.3G 2.0K 1.3G 0% 1 181885 0% /usr/src > sodium# cat /etc/fstab > 5fd63b50b0c6cb1d.a / ffs rw,softdep,noatime 1 1 > 5fd63b50b0c6cb1d.d /tmp mfs rw,async,nodev,nosuid,-s=64m 0 0 > 5fd63b50b0c6cb1d.e /var ffs rw,softdep,noatime,nodev,nosuid 1 2 > 5fd63b50b0c6cb1d.f /usr ffs rw,softdep,noatime,nodev 1 2 > 5fd63b50b0c6cb1d.d /usr/tmp mfs rw,async,nodev,nosuid,-s=64m 0 0 > 5fd63b50b0c6cb1d.g /usr/X11R6 ffs rw,softdep,noatime,nodev 1 2 > 5fd63b50b0c6cb1d.h /usr/local ffs rw,softdep,noatime,wxallowed,nodev 1 2 > 5fd63b50b0c6cb1d.j /usr/obj ffs rw,softdep,noatime,nodev,nosuid 1 2 > 5fd63b50b0c6cb1d.i /usr/src ffs rw,softdep,noatime,nodev,nosuid 1 2 > sodium# top|head > load averages: 0.08, 0.02, 0.01 sodium.bkis-orchard.net 13:12:00 > 52 processes: 1 running, 50 idle, 1 on processor up 14 days, 5:21 > CPU: 0.1% user, 0.0% nice, 0.3% sys, 0.0% spin, 0.3% intr, 99.3% idle > Memory: Real: 35M/110M act/tot Free: 127M Cache: 46M Swap: 0K/548M > > PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND > 59735 root 10 0 0K 19M sleep bored 44:53 0.44% softnet > 65312 root -22 0 0K 19M sleep - 339.9H 0.00% idle0 > 57981 root 10 0 0K 19M sleep bored 7:56 0.00% sensors > 39371 _unbound 2 0 12M 10M sleep kqread 1:33 0.00% unbound > sodium# cd /tmp > sodium# ls -l > total 4144 > drwxrwxrwt 2 root wheel 512 Jun 16 07:51 .ICE-unix > drwxrwxrwt 2 root wheel 512 Jun 16 07:51 .X11-unix > -rw-r--r-- 1 root wheel 1499861 Jun 30 12:31 lynx-2.8.9rel1.tgz > drwxr-xr-x 2 root wheel 512 Jun 16 07:51 sndio > -rw-r--r-- 1 root wheel 564428 Jun 30 12:31 tcsh-6.20.00p1-static.tgz > drwxrwxrwt 2 root wheel 512 Jun 30 12:33 vi.recover > sodium# > sodium# pkg_info > sodium# > sodium# which pkg_add > /usr/sbin/pkg_add > sodium# pkg_add -vv tcsh-6.20.00p1-static.tgz > Fatal error: Can't write session into tmp directory > at /usr/libdata/perl5/OpenBSD/PackageRepository.pm line 1025. > sodium# env > _=/usr/bin/env > LOGNAME=root > PWD=/tmp > HOME=/root > OLDPWD=/tmp > SSH_TTY=/dev/ttyp0 > TOP=-S -i -s1 > MAIL=/var/mail/root > SSH_CLIENT=192.168.105.0 4099 22 > > PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin > TERM=xterm > SHELL=/bin/ksh > SSH_CONNECTION=192.168.105.0 4099 192.168.105.62 22 > USER=root > sodium# cd /tmp > sodium# touch foo > sodium# ls -l foo > -rw-r--r-- 1 root wheel 0 Jun 30 13:07 foo > sodium# /bin/rm foo > sodium# > sodium# cd /var/tmp > sodium# touch foo > sodium# ls -l foo > -rw-r--r-- 1 root wheel 0 Jun 30 13:08 foo > sodium# /bin/rm foo > sodium# > sodium# cd /usr/tmp > sodium# touch foo > sodium# ls -l foo > -rw-r--r-- 1 root wheel 0 Jun 30 13:13 foo > sodium# /bin/rm foo > sodium# > > Thanks in advance for any assistance,
