Hi LDM User,

Version 6.13.13 of the LDM has been released. You can get it from the
LDM's website, <https://www.unidata.ucar.edu/software/ldm/>.

Besides adding some MRMS parameters to the GEMPAK NSSL table for NOAAPort
ingestion, the main change is in the pqact(1) utility. From the CHANGE_LOG
file:

    pqact(1):
        * Hopefully closed a tiny window-of-vulnerability in which a SIGALRM
          might be generated after a successful write(2) to a (very) slow
          decoder but before the alarm is dismissed -- leading to the
abnormal
          termination of the process. This has occurred at more than one
site.
        * Set default SIGALRM handing to "ignore" just in case
        * Documented "-t <timeout>" option for piping to a decoder
        * Added decoder command to pbuf_flush() log messages

If you've experienced mysterious termination of a pqact(1) process due to a
SIGALRM (usually signal 14), then you should update to this version.
