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.
Regards,
Steve Emmerson
