[LDM #XIP-610331]: repeated imuxsock messages in system log

OK.

Where LDM pattern-action file actions will write to disk is a function of how
one sets up those pattern-action files.  The LDM does not have any preconceived
notion of where files should be written to disk.  In fact, LDMs don't need to
write to disk at all (other than to the LDM product queue).

I am guessing that all references to /data_store come from the package you
are trying to run, and that is AWIPS-II.

Are you asking for help in setting up AWIPS-II data ingest?  If yes, that is
a question best posed to address@hidden, not address@hidden.

Very good.  The LDM log files really should be owned by the 'ldm' user.

re:

??? LDM logging messages will be sent to the LDM and system log files if the
SELINUX setting being used is permissive:

/etc/selinux/config

SELINUX=permissive

We recommend using the 'disabled' setting instead of 'permissive' or 
'enforcing':

SELINUX=disabled

NB: changes made to /etc/sysconfig/config will take effect after a reboot, not 
before.

re:
>    Now that I changed the permissions to ldm:ldm, it works better.

Very good.

The imuxsock logging rate limiting appears to be something that one has to setup
themselves on Linux systems using current versions of rsyslog.  We do not turn
on logging rate limiting on our systems, so we are not familiar with the type of
messages that you included above.

Question:

- did you or someone else at GSD setup imuxsock rate limiting in 
/etc/rsyslog.conf?

  If yes and the person was not you, you should contact him/her to find out
  what to do next.

re:
> Thanks again ,--Vivian

No worries.  Sorry we couldn't be of more help, but the things you are running
into are outside of the LDM per se.

Cheers,

Tom
