HEALTH NOTICE: eDir Threads?


Hi all, we are constantly seeing these in the messages file and I am not
sure what to look into. What would eat up all the threads? and I don't
know what File Handles are. The server(s) seem generally healthy but the
warnings continue day and night. They switch from "Healthy" to "Suspect
or Unknown" and then back to "Healthy" a minute or less later. Below are
the two warnings, (File Handles and eDir Threads). Any help would be
great. Thank you.

HEALTH NOTICE: File Handles changing health status from Healthy to
Unknown

HEALTH NOTICE: eDir Threads changing health status from Healthy to
Suspect

File handles are the ways that programs access files. They use a
path/name to access the inode, and from there use a file handle (in the
form of an integer) that is specific to that file to access things. You
can see this by using strace and watching just about anything since
files are always being opened/closed for even trivial things:

/usr/bin/strace -e 'open' echo hi

The lines like the following are opening files and returning (after the
'=' character at the end) the file handle that will be used later in the
program for reads and such (filtered out of this output):

open("/etc/ld.so.cache", O_RDONLY) = 3
open("/lib64/libc.so.6", O_RDONLY) = 3

Anyway, are these messages coming from ndsd? Could you post the full
line(s) from /var/log/messages to show some of their source? If the
server is working properly I'd probably ignore it since it probably just
means things are working hard but within what you'd consider acceptable.
You can increase the number of eDir threads possible, but it would
probably be useful to figure out the source of these messages for sure
(ndsd, vs. some other monitoring process, vs. the system itself) as well
as what the system is doing eDir-wise (IDM, big LDAP server, file server
running OES 11, etc.).

Good luck.

Thank you for the reply. It is a SLES 10 server and is a root server for
a file and print tree.

Ah... edirmon is doing this, which I thought might be the case. Well,
then it's up to you. I think edirmon can have its thresholds modified
so you may want to bump them up a bit to be a little more tolerant of
your system. Considering this warning goes back and forth from 'Health'
to 'Suspect' it sounds like your box is just busy sometimes and working
properly.

Good luck.
