Package: libc6
Version: 2.3.6.ds1-13
Severity: normal
Tags: patch

On 64bit machines, svc_getreqset ignores filedescriptors 32-63 and others.
This has been fixed in glibc 2.4 but needs to be
fixed in 2.3.6.debian while we keep using it. 
The consequence of this bug is that if mountd (or any other rpc server) 
gets 26 or more concurrent tcp connections, it goes into a spin constantly 
using CPU, and not servicing requests on those connections.

Following patch fixes it.

Thanks,
NeilBrown

Thanks, the patch has been added to our SVN, but it probably won't be
fixed until the release of Debian 4.0r1.

I am closing the bug with the version from experimental, which has the fix.
