Hi all I have 2 OI installations in kvm/qemu virtual machines. Both are showing the same symptom: The available swap/stack space is continuously decreasing, up to the point (roughly every 6-7 weeks) where none is left and no new processes can be forked. Meaning a forced reboot, as also no login shells can be spawned any more. I have already moved /tmp to a separate dataset in the global zone (and to plain directories within the two other zones).
What I see is a slow, continuous decrease in the sisze of all file systems marked as swap (~6.5 GB after reboot): df -h | grep swap over the last 24 hours: swap 6.45G 1020K 6.45G 1% /etc/svc/volatile swap 6.45G 60K 6.45G 1% /var/run .. swap 5.94G 1020K 5.94G 1% /etc/svc/volatile swap 5.94G 60K 5.94G 1% /var/run .. swap 5.89G 204K 5.89G 1% /etc/svc/volatile swap 5.89G 12K 5.89G 1% /var/run .. swap 5.62G 204K 5.62G 1% /etc/svc/volatile swap 5.62G 12K 5.62G 1% /var/run .. swap 5.04G 1020K 5.04G 1% /etc/svc/volatile swap 5.04G 48K 5.04G 1% /var/run The swap device on the other hand remains stable: # swap -lh swapfile dev swaplo blocks free /dev/zvol/dsk/rpool/swap 270,2 4K 512M 512M As nothing seems to get stored in that space, I assume it must be used by something else (processes not freeing it). Does anybody have an idea on how to start debugging this? All I get in the log files are these messages, starting some hours before the boxes stand still: Feb 14 03:51:09 xfer-srv05 tmpfs: [ID 518458 kern.warning] WARNING: /etc/svc/volatile: File system full, swap space limit exceeded Feb 14 03:51:10 xfer-srv05 last message repeated 1 time Feb 14 04:03:20 xfer-srv05 genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 8106 (httpd) Feb 14 04:28:36 xfer-srv05 genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 8920 (httpd) Feb 14 05:58:20 xfer-srv05 genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 11050 (httpd) Feb 14 05:58:24 xfer-srv05 last message repeated 1 time Thanks for any ideas. /markus _______________________________________________ openindiana-discuss mailing list openindiana-discuss@openindiana.org https://openindiana.org/mailman/listinfo/openindiana-discuss
