Subject: linux-image-2.6.26: copying /proc/*/pagemap leads to resource
consumption because of uninitialized struct
Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-10
Severity: normal
File: linux-image-2.6.26
*** Please type your report below this line ***
The VMware support script copies various files from /proc to the report
directory. Copying
/proc/*/pagemap takes forever and produces a large file, probably filled with
garbage.
Steps to reproduce:
# cp /proc/self/pagemap /tmp/self.pagemap
I found a LKML thread regarding the problem:
