[Datastream #OKF-212399]: core dumps on unidata2-new

From the /var/adm/messages line

Aug 19 18:03:14 unidata2-new.ssec.wisc.edu genunix: [ID 603404 kern.notice] 
NOTICE: core_log: dcgrib2[20848] core dumped: 
/data/core/core.dcgrib2.20848.u8858

I trace process ID 20848 to the following entries in ~ldm/logs/ldmd.log

Aug 19 18:03:14 unidata2-new.ssec.wisc.edu pqact[18665] ERROR: pipe_put():

terminated by signal 11

and in ~ldm/data/gempak/logs/ I see the dcgrib2_fnmoc.log file was over 2 GB in 
size!  I created a new logfile for the fnmoc feed and so far have not see any 
further DCGRIB -11 errors in the new log.  I think this problem was caused by 
not rotating the GEMPAK grib decoder logs.
