Hi Leonard,

The typical things to look at WRT LDM logging on Linux systems are:

- SELINUX setting

  The setting in /etc/selinux/config should be:

  SELINUX=disabled

  NB:

  - there should be only one uncommented entry for SELINUX in the
    config file

  - the machine typically needs to be rebooted after the SELINUX
    is changed

- check the ownership of the LDM log file; it should be owned by
  the user running the LDM (e.g., 'ldm'), not 'root'

- if the two items above all look correct, I would rebuild and
  reinstall your LDM:

  <as 'ldm'>
  cd ~ldm/ldm-6.10.1/src
  make distclean
  ./configure && make install

If logging is still not working after addressing the items above,
please send us the output from:

uname -a

printenv

ls -alt ~ldm

I have never seen this situation.  Are you sure that you are looking
in the correct output directory for your 'pqact' instance(s)?

Check /etc/selinux/config.

OK.

re:

'syslog' on  CentOS 6, not 'rsyslog'?  I run LDM 6.10.1 under CentOS
6.2 x86_64, and the system logging daemon is 'rsyslogd'.

Cheers,

Tom
