We also need the output of "bt" at that prompt. Also, is this i386 or amd64?
-
Will do the bt at the prompt next crash.

None of that tells us if you used a 32-bit (i386) or 64-bit (amd64) snapshot.
-
i386, sorry, I didn't realize the amd64 snapshot would run on a pentium D.
-
It may, it may not, I'm not sure what that CPU can do… but it's always best to provide the information requested rather than relying on people to guess what you may have done based on the hardware you have.

Ok i think i got even this one handled.
Wait for the next snapshot and report back. -
2.0-BETA5 (amd64) built on Fri Feb 11 06:51:36 EST 2011 : I was able to add a CARP IP to the master (2.0-BETA5 (amd64) built on Fri Jan 21 23:51:34 EST 2011) and the slave got it but then I've added a certificaton autority on the master and the slave crashed.
By the way: if I add the CA to my primary host, should I be able to use it from the slave right?
thanks

Hi Guys
I keep getting a kernel panic:
pf_state_tree_id_RB_REMOVE_COLOR+0x25 empl
This keeps happening every so often.
Anything I can do?
Kind regards

Make sure both of your firewalls are on the latest snapshot and try again. Those panics should be cleared up.

Upgraded the slave to 2.0-RC1 (amd64) built on Sun Feb 13 23:53:14 EST 2011.
Crashed after installing autobackup package on master (sync started and slave crashed): I'm really scared to upgrade the master node to the EC1 as I've already put the cluster in production…is the commercial support going to support me even if I'm running on 2.0? thanks
-
Yes, commercial support will assist you even if it's 2.0. Your panic is different than the previous posted in this thread though.
-
Ok,
I'll try to upgrade the master node in two hours. Thanks -
Can you describe please your setup?
EDIT: I put even more safety belts so your carp panic should not happen on new snapshots.
-
Hi, I'll open a ticket tomorrow with all the details on my setup. By the way, I have the 2 nodes running 2.0-RC1 (amd64) built on Sun Feb 13 23:53:14 EST 2011 for a few hours without problems. I didn't work on any new carp ips, only on openvpn: the master was synced to the slave many times without problems. I'll try to play more with carp tomorrow and let you know :-)
thanks -
(Ticket #KZZ-134399 opened)
I have the cluster in production for 1 day without any problem right now.
Here is one strange thing I've seen in the logs (on the slave) the other day, what happened?Feb 13 22:14:50 kernel: vip7: link state changed to DOWN

The next snap (building now) should have more carp panic fixes.
Not sure about the crazy kernel message there, though it looks like maybe it was two messages overlapping, but a bit more corrupt than that usually is.
-
I would like to inform that since its updating on Sunday (when the snapshot server was available again), the Dell P4 with the integrated em gigE, I have not recieved any panics and the machine is running well. Thank you all for all the hard work fixing the issue! :D

Hi,
Like cyber7, I'm getting kernel panics (pf_state_tree_id_RB_REMOVE_COLOR, pfpurge is always the current process) since two weeks (approx. 2 to 3 times a week) on a VMWare setup. Here's a screenshot :
-
spacelui,
amd64 or i386? snapshot date? What type of setup, CARP? Multi-WAN? anything special going on with FTP/PPTP? Any more detail might help. Posting the same panic that someone else had doesn't help much (unless you also have the bt output to go with it) but if we can track down what about your setup might be related to the panics, that would be more helpful. What we need is to find some commonality between the people still getting them.
