Greetings, alpha managers. We are observing odd behavior on a
non-clustered 5.1A system (es40) as follows.
In the /tmp directory, the command:
"ls -l"
lists 18 files. However, a user knew he had put 19 add'l files (18
directories and 1 gzipped tarfile) there, and could demonstrate this by
entering the command:
"ls -l [name of invisible file]"
Subsequent investigation, based on running the command:
"strings /tmp"
and sorting through the output shows 1,123 add'l files in /tmp, all of
which can be listed. All are readable files, most are owned by root and
are of the form:
-rw------- 1 root system 16 Sep 2 2003 /tmp/sh57582.Fnwp2
-rw------- 1 root system 9 Sep 2 2003 /tmp/sh57582.RsFt3
-rw------- 1 root system 1820 Sep 2 2003 /tmp/sh57582.DadJ4
with contents generally being what looks like strings from a command.
There are also a few user files, with actual user text content.
There is a total of 29 subdirectories in this directory.
I really can see nothing odd about these files, other than their
invisibility. The sum total of files in the directory appears to be
about 3,486. Seems like a lot, but a summary I read said:
"you should be able to create about 32768 subdirectories before the
limit is reached. Note that this limit is irrelevant to regular files,
since files do not use hard links as directories do. Some responders
said they had directories containing up to 40,000 files, with no
problem."
Does anyone have any suggestions as to what might be going on here?
TIA;
