Subject: ***SPAM*** Re: [ldm-users] LDM 6.13.0 released
Jeff,
Glad to hear you got it working.
The error-messages you got relate to the shared-memory segment that holds
metadata on all the upstream LDM processes. When a problem occurs with this
shared-memory segment, it's usually because someone or something has deleted it
(the ".gemenviron" script is notorious for deleting all shared-memory segments
that it can -- even ones that it shouldn't).
It's also possible that the O/S managed to mess-up access to the segment
(we've seen this on some virtual machines in the cloud).
Please contact support-ldm@xxxxxxxxxxxxxxxx if you encounter further problems.
Regards,
Steve Emmerson

Dear LDM user,
Version 6.13.0 of the LDM is now available at the following URL-s:

As you can see from the attached CHANGE_LOG file, the major new feature
with this release is a new logging system. The previous system used the system
logging daemon by default; the new system doesn't. Instead, it writes directly
into the standard LDM log file by default. This change was made because the
previous system caused problems and wasn't 100% reliable (see the attached
CHANGE_LOG file for details).
The format of log messages is slightly different. Here's an example of
a log message from the previous system:
May 02 2016 20:16:25 chico.unidata.ucar.edu
oliver.unidata.ucar.edu(feed)[14078] NOTE: Starting Up(6.12.14/6):
20160502191624.896 TS_ENDT {{ANY, ".*"}}, SIG=b12852828dac75021ac15b7064439754,
Primary
And here's that same type of message in the new format:
20160429T155919.718276Z oliver.unidata.ucar.edu(feed)[21104] NOTE
up6.c:445:up6_run() Starting Up(6.13.0/6): 20160429145918.709017 TS_ENDT {{GPS,
"(.*)"}}, SIG=f2693a8f53ba6736843a5300e30b68fd, Primary
Note the timestamp is now in ISO 8601 format (which should make sorting
easier). It also has microsecond resolution and is guaranteed to be in the UTC
timezone. Note also the field containing the local hostname is missing (it was
added by the system logging daemon) and a new field has been added that
specifies the location where the message was generated in the form
file:line:func().
Aside from slight differences in the format of log messages, you should
be able to use the new logging system just like the previous one. In
particular, you will still be able to send an LDM process a SIGUSR2 signal to
rotate its logging level and the command ldmadmin newlog should still create a
new LDM log file and rotate the names of the old ones.
The old logging system still exists in the LDM library for
backward-compatibility with third-party developers.
Besides the new logging system, this version also has several other
improvements and bug-fixes. See the attached CHANGE_LOG file for details.
Regards,
Steve Emmerson
