[SSI-users] openssi amavis problems

[Karsten N. <ka...@ww...>]

Hi,

I am trying to install amavisd-new on openssi 1.9.4 installed from 
http://www.atlantech.com/~john/openssi-etch 

I have installed amavisd-new with out problems and added the binary 
to /cluster/etc/loadlevel

amavisd-new seems to die when scanning files extracted 
to /var/lib/amavis/tmp/xxx/part/xxx

and when I try to manually remove these files the system hangs for a very long 
time before the files gets removed.

has anyone any suggestions ?

thanks in advance

Regards
- karsten

It looks like I've got a bug somewhere in the cfs code.

When you remove the files what state is the rm in?

(as shown by "ps -l").

The amavisd-new process gets an in recoverable error and the process is killed 
by the master process. It is only the processes that has been migrated to an 
other node that has this problem.

The state of the rm is D. And is the same problem as described as above. When 
I shutdown the nodes that has been running amavisd-new the rm goes fine with 
no delay at all.

If it is to any help ps -l reports WCHAN to be svrcfs on the dead rm process.

Yup.  Looks like the cfs code is forgetting to do something.

Maybe I dropped some code on the floor when I ported the OpenSSI patches 
to 2.6.12, or maybe 2.6.12 needs something extra.

I'll need to think about ways to find out what's going on.

I'd guess that if you look at /proc/XXX/wchan you'll find it's in 
svrcfstok_remove_notify.

The problem is still the same. The rm process has D+ state and 
the /proc/xxx/wchan reports svrcfstok_remove_notify on that process.

Roger Tsang has sent me a patch that may fix this problem.

Could you please try it, do:

    apt-get update
    apt-get dist-upgrade

and reboot.

Drat.

Just in case, do:

# uname -r -v

should be:

2.6.12-ssi-686-smp #1 SMP Fri Jun 27 19:20:41 UTC 2008

# dpkg -l linux-image-2.6.12-ssi-686-smp

should be

Any chance you could re-try this with the packages currently on 
http://deb.openssi.org/alpha/openssi-etch?

There is a new kernel that's working better for me.

Re: [SSI-users] openssi amavis problems

[Walker, B. J (HP-Labs) <bru...@hp...>]

In case you haven't already tried:
1. try it without loadlevel;
2. try running it on a node other than the node where the files are stored;

Are the files in question open by the application when you are trying to remove them?
