Package: kernel-source
Version: 2.6.8_16sarge6
Severity: important
Maybe this is related to http://bugs.debian.org/255931 (and concomitant
discussion on [email protected]). I only guess that this is caused
by a "spurious" ESTALE error return.
Running on machine "rome", as "plain user" psz:
while :; do date; perl -e 'mkdir "tdir"; chdir "tdir"; open F, ">tscr"; print F
"echo hello; sleep 2; /bin/pwd; echo bye\n"; close F; system "sh tscr";
mkdir("dir$_"),rmdir("dir$_") foreach 1..100; system "sh tscr"; unlink "tscr";
chdir ".."; rmdir "tdir"'; done
and (also on "rome"), as root:
while :; do date; lsof | grep psz | grep -E 'cwd|deleted|dir' | grep -v xterm;
sleep 1; done
occasionally produces
