reexec socketpair: No buffer space available
Hi all, Has anyone come across this error before: sshd[20861]: error: reexec socketpair: No buffer space available It stops remote users/services to connect to the machine remotely. I have 17 jails running on the machine. CPU load on the machine is low, and RAM usage is also low (16GB avail, 5GB Active) System info: FreeBSD 8.0-RELEASE-p6 FreeBSD 8.0-RELEASE-p6 $ netstat -mb 1029/4101/5130 mbufs in use (current/cache/total) 514/3446/3960/65536 mbuf clusters in use (current/cache/total/max) 0/1536 mbuf+clusters out of packet secondary zone in use (current/cache) 0/1582/1582/12800 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/6400 9k jumbo clusters in use (current/cache/total/max) 0/0/0/3200 16k jumbo clusters in use (current/cache/total/max) 1285K/14245K/15530K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 373686 requests for I/O initiated by sendfile 0 calls to protocol drain routines What else should I be looking for to help me trouble this?

load average with multi-core CPU's
Hi all, Can someone explain, or point me to correct documentation on what the load average on top/uptime is actually displaying? Is the load the average amount of processes waiting to execute on the server, or is it independent of CPU? Am I correct with the below statements? * Example 1: 1 CPU, load average of 1.00, CPU at capacity. No processes have to wait to execute. 1 CPU, 2.00 load average, 1 process is waiting to execute. * Example 2: 1 CPU, 4 cores. load average of 2.00. 2 cores are working at capacity, other 2 are idle (mostly). 1 CPU, 4 cores, load average 5.00. 4 cores are at capacity, 1 process waiting to execute. I tried searching, but I couldn't find much besides some blog postings.

Thanks- That's what I thought it was. I'm trying to settle an argument at work : ) On Thu, Sep 22, 2011 at 3:29 PM, Mark Felder f...@feld.me wrote: On Thu, 22 Sep 2011 10:22:43 -0500, Henry M henr...@gmail.com wrote: Hi all, Can someone explain, or point me to correct documentation on what the load average on top/uptime is actually displaying? Load average is average number of processes in the run queue for the 1, 5, and 15 minute intervals. If you have a quad core CPU a 4.00 load average means you've been keeping the CPU busy at 100%. Does that make sense?

Re: ZFS and NFS or CIFS
Hi Chris, If you are transferring data from a Windows machine, your best bet would be to use SAMBA. Windows communicates with samba pretty easily. You essentially just mount a network drive, and transfer the files you want. Here are a few links to get you started: http://www.freebsd.org/doc/handbook/network-samba.html http://www.freebsddiary.org/samba.php The samba configs are pretty straight forward, you just need to make permissions are correct. Good luck! Regards, Henry On Fri, Aug 19, 2011 at 1:43 AM, Chris Brennan xa...@xaerolimit.net wrote: Greetings! I have several ZFS volumes set up on my FreeBSD 8.2 (32-bit) server at home and I am trying to figure out how to set up a NFS and/or CIFS share of the various volumes I have created and for the life of me, I can't figure it out. I don't really care which one or both right now (I should learn both). I just have tons and tons of data to move from my Windows desktop to this server and I'd like to use something other then SFTP, even over my LAN, it's very slow.
