Description David Juran 2002-07-18 11:29:44 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020513

Description of problem:
We have a small testcase where we do several consecutive mmap:s and remove:s on
an NFS-mounted file. This causes the system to become unresponsive. It does
answer to ping, but nothing else works and it has to be rebooted.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. g++ -s -O3 -Wall tt.cc -o tt
2. move to an NFS-mounted directory
3. run tt

Additional info:

You might have to run tt several times to cause the freeze. Probably depending
on the load of the network. You might have to adjust the filesize in order to
reproduce the error.
