OK, there's memory, and then there's memory. The amount of swap you have, the fact that it's 4.5, and the amount of RAM you have imply to me that the problem is that you are out of pmap entries. You should up your KVA space to 2G or maybe even 3G; the default in 4.5 was 1G. Basically, I now think that you don't have enough memory to map how much memory and virtual memory you have. Amusingly enough, you might actually have *better* luck with a lot less swap... If your KVA space is already enlarged above the default, then you can ignore this and just go ahead with the debugging to see what the wait channels for all the processes that won't run are stuck at. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
