Hi Ingo,

With patch-2.6.14-rt1 I notice below problems:

1).
I'm observing a major system slowdown after several hours of uptime.
This is a normal workstation (running kde, gcc, etc.).
Once I got on all open terminals an error message:
`VFS: file-max limit 51078 reached` and it freezed.

2).
During `scp bigfile to another machine` I get an oops:
http://149.156.124.14/~pluto/tmp/2.6.14-rt2-oops.jpg [796 kB]

Any ideas?

Reagrds,
Paweł.

Thx, -rt4 works fine.
