imaging Ubuntu 6.06, having "buffer" errors.
Hi guys. Searched for this kind of thing, but can't find it. Have openvz installed; imaging Ubuntu 6.06 LTS off of it. My problem is this: After about 2-3 hours, or about 80 connections from UnrealIRCD(I'm testing Ubuntu for ircds), the box locks up, networking wise.. You can't SSH into the box. The SSHD server is fine, running, and listening for connections. You can restart the SSHD sever.. makes no difference. The SSH server DOES work after a fresh system restart. Something is killing it. This is what you get if you try to SSH into the imaged Ubuntu after it "locks up" ssh admin@XX.XXX.XXX.XXX ssh_exchange_identification: Connection closed by remote host wastedfluid@wastedfluid:~$ However, if you "vzctl enter 102" and enter the box - you can ping. This is what happens when I tried to SSH into the Imaged Ubuntu 6.06LTS from itself via "vzctl enter 102" root@jbodystreet:/# ssh admin@XX.XXX.XXX.XXX ssh: connect to host XX.XXX.XXX.XXX port 22: No buffer space available root@jbodystreet:/# UnrealIRCD can still accept incoming connections from the Ubuntu. You get errors such as "No buffer space available" .. I "vzctl enter 102" as root on the Imaged Ubuntu6.06LTS, and I couldn't even ssh out, or ping out, just kept getting "No buffer space available"

cat /proc/user_beancounters 'duplicate problem' cat /proc/user_beancounters any failcnt increases? Rick
there are failcnt's, but is there an increase? note that I told you to run it twice for a reason.
ok, now increase the ubc metric that has increased failcnt. Rick

read the ubc wiki page in my sig, then run: vzctl set 102 --tcpsndbuf 2589488:3589488 --save
