To recap to save you going back through history - After running 9.0 - 9.2 for 3 years I upgraded to 10.1RC3 and started getting a locking issue, most new processes fail to start, top and ps failing being indicators, the most info I have got is a back trace using kgdb, there are 4 instances I got output from procstat -kk -a On several occasions I have found that after inserting a usb memstick the device failed to be created, leaving me unable to mount the filesystem without a restart. I then switched to stable/10 in hopes of a fix finding it's way in. The back traces I have been able to collect (and a dmesg) are listed at http://shaneware.biz/freebsddebugdata/ This is my everyday desktop machine. I am now running FreeBSD leader.local 10.1-STABLE FreeBSD 10.1-STABLE #11 r283839: Thu Jun 4 17:41:28 ACST 2015 root@leader.local:/usr/obj/usr/src/sys /GENERIC amd64 I can only say it appears to be getting worse, though I may just be getting sick of having to restart nearly every day. Lately it seems that the less I do the quicker it locks up. I have restarted twice this week and then let it sit while I have gone out, after returning I get maybe 10-15 mins then have to restart, one of them was less than an hour uptime. While running poudriere I have got past 1 day uptime but it locks up harder and I don't usually get a chance to record any data. -- FreeBSD - the place to B...Software Developing Shane Ambler
