Greetings, fellow Toaster-ites.
Hopefully this will distract you from the previous l1nux4411 "I'm 16 and Linux r00lz" troll-fest ...
We've got a creaky old F740 running 6.3.1R1 that's performed yeoman duty for us for many years.
All of a sudden it's having regular (at least once an hour) issues with "No buffer space available" errors that cause temporary NFS mount hiccup issues. I'm not sure how bad the situation is but it hasn't happened to us before (we also had our first panic on the F740 the other day, too) and more to the point, a reboot didn't fix the problem - it came right back shortly thereafter. Which is what worries me - a reboot should've fixed the issue, at least for awhile. I'm also troubled that there doesn't seem to be any tunable options parameter to increase the number of kernel buffers (or kernel buffer space in general) to deal with this issue.
Has any other Toaster-ite run into this before?
Here's the configuration and the error messages below.
Thanks,
- Greg Earle
