Bug#489613: openafs-modules-source: attempt to reinsert module results in Cannot allocate memory
FWIW, my Debian stable machine just started exhibiting this problem after months of perfect operation; persisted across reboots too. Switching to the 1.4.12.1+dfsg-2~bpo50+1 openafs suite in lenny-backports appears to have resolved it. uname -a: Linux ... 2.6.26-2-686 #1 SMP Mon Jun 21 05:58:44 UTC 2010 i686 GNU/Linux Thanks for the suggestion!

Bug#489613: openafs-modules-source: attempt to reinsert module results in Cannot allocate memory
Hi folks, Several of you reported this problem with reinserting the OpenAFS module around the 1.4.7 version that shipped with lenny. If you're still having trouble with this, could you try the 1.4.11 version that's available from backports.org? I think the problem may be solved. I was able to reproduce this problem on an amd64 system before, but I can't reproduce it any more with the current module. -- Russ Allbery (r...@debian.org) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Just to make sure, you're not loading the kafs module that comes with the kernel for some reason, are you? -- Russ Allbery (r...@debian.org) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

How long have you waited on AFS when this happens? Talking this over with upstream, the general consensus is that it shouldn't take longer than a few minutes for AFS to figure it out; if it takes longer than ten minutes, there's definitely some other bug here that we'd like to get to the bottom of. (That may still be too slow, I realize, but I'd like to get a handle on whether AFS is just being too slow to realize that its IP address has changed or whether it's really getting completely stuck. We may be able to fix both problems, but need to understand first which problem we're dealing with.) BTW, this bug is almost certainly present in earlier versions of AFS as well; AFS has leaked memory in one way or another for quite a while on module reload. Only recently has it gotten a facility for realizing that it's done so. -- Russ Allbery ([EMAIL PROTECTED]) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I can't duplicate this on any of my systems at the moment, but I have seen this after some period of time of testing various versions without a reboot and the AFS module does tend to leak at least some memory when it's unloaded. I suspect that eventually it fragments the kernel's internal memory allocator. (The Linux kernel interface keeps changing and it's very hard to keep up with the changes in areas like this.) I suspect the system will be fine after a reboot. Unloading and reloading the module *mostly* works but is not the best thing to do when it can be avoided. It's not something that I consider critical to support, although I'll report this upstream and hopefully someone will have a chance to take a look and figure out where we're leaking memory. If you have more useful debugging information (dmesg, for example), that will be helpful; I can provide upstream with the details of the memory leak that I see, but I can reload the module anyway. -- Russ Allbery ([EMAIL PROTECTED]) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
