[OpenAFS-devel] free(): invalid pointer with bos shutdown, kernel panics when shutting down, and loss of volumes when adding additional servers, in 1.2.11 and 1.3.64

[Brett L Trotter]

We've been experimenting with AFS 1.2.11, 1.3.64 and now 1.3.65 more or less 
simultaneously. We've been trying to implement the same things in the stable 
1.2.11 release that we are doing in 1.3.64, obviously with some different 
pieces involved, like with gssklogd on the 1.2.11.

In any case, we're seeing a lot of problems in both 1.2.11 and 1.3.64

First of which is a bunch of free(): invalid pointer 0x-------- when doing bos 
shutdown: one for each service running. This happened on a 1.2.11 box and 
1.3.64 box, but not on another 1.2.11 box.

Next, when doing /sbin/service shutdown localhost -localauth -wait  in some 
cases (after doing bos shutdown localhost -localauth or bos shutdown 
localhost with a token), the system kernel panics- in both 1.2.11 and 1.3.64. 
I have not found a unique and certain sequence of events to replicate this 
with 100% failure.

When we've been trying to add an additional server, they don't seem to get 
quorum'd properly and sync up their databases, and twice now the machine that 
was the first server and had ~10,000 test user volumes has lost -all- of the 
volumes. The machine comes back up and says salvaging, which takes forever as 
expected, then the filesystems come online, and yet nothing is there. a bos 
shutdown then takes a split second, which usually takes a while.. and when 
you bring up the services again it goes back to salvaging.

Can someone tell me the adding an additional server for dummies quickstart 
guide? The OpenAFS.org docs on that are either a little sketchy, something 
doesn't quite go as written, or I am just misunderstanding something.

The free(): invalid pointer errors seem harmles.. The kernel panics and loss 
of volumes worry me. Am I doing something completely crazy?
