Thank you so much for your prompt reply. As a follow up to your response- will this problem "go away" for kernel version 2.6.33? If so, perhaps I can upgrade to that version.
As an alternative- can I fix this by downgrading the kernel to some lesser version (say 2.6.30)? By the way, this issue has bitten me in the past by causing my system to create such large /var/log/messages files that the filesystem reached 100%. I fixed that by adding :msg, contains, "ima_file_free" ~ :msg, contains, "iint_free" ~ to /etc/rsyslog.conf as per an earlier suggestion of yours. I found I needed pam-afs-session; is the library provided in the rpm going to be included in the default openafs packages? Lastly- since I run Fedora, which now provides openafs by their own repositories, which repository would you recommend- theirs or yours? --- On Mon, 3/15/10, Simon Wilkinson <[email protected]> wrote: > From: Simon Wilkinson <[email protected]> > Subject: Re: [OpenAFS] multiplt kernel call traces > To: [email protected] > Cc: [email protected] > Date: Monday, March 15, 2010, 8:45 AM > > On 15 Mar 2010, at 13:35, [email protected] > wrote: > > > I'm getting many, but I mean, many call traces with > openafs on my Fedora 12 x86_64 system running recent > kernels.
