RPC: Unable to allocate resbuf from cache! - revisited

RPC: Unable to allocate resbuf from cache! - revisited

[Dan Yocum]

Hi all,

Looking back at the archives=20
(http://marc.theaimsgroup.com/?t=3D101707335800002&r=3D1&w=3D2) I see tha=
t you=20
(Trond) say that these copious "RPC: Unable..." messages shouldn't be a=20
problem.  Could they be a problem?

The reason I ask is, occassionally, we're getting these strange files=20
created with 0 size, date, and some gobble-dee-gook names, and they just =
so=20
happen to show up when we get this error message in the logs.  Here's wha=
t=20
one looks like:

bash-2.04$ ls -l |egrep -v '(fit|ps|fp|mem)'
total 5742612
-rwxr-xr-x    1 jen_a    sdss            0 Dec 31  1969
:N=A8TL8=D5 =E4=F0=FF=FF=EB=FE=FF=F5@                                    =
  =A6,

The rest of the files are OK, but this is slightly disconcerting.

This is 2.4.18 + XFS + NFS_ALL - rpc_tweaks, IIRC (it's been a long time =

since I've built this kernel). The system has 2GB RAM and 4GB swap (himem=
 is=20
  enabled).

Any thoughts?

Thanks,
Dan

That's totally unrelated to the above message, and looks rather like a
server bug. Is the server also 2.4.18+XFS?

Cheers,

Yes, the error message is on the server system and it is running 2.4.18+X=
FS.

I guess I didn't realize that the error message is being created by the c=
lient.
