Hi,

I've got a problem writing data to AFS using an OpenAFS-1.3.73-Client
on Linux (Kernel 2.6.9, Debian GNU/Linux). Read access seems to work fine,
i read >10 Gigabytes successfully. But after writing some data (some
Megabytes), I Get this error message:

 rxi_AllocPacket: packet not free

and a Kernel Oops (it's attached to this mail).
Is there a solution for this problem?

Regards,

Frank
