Gabe, The problem appears to be the last entry in your pqact(1) configuration-file: DDPLUS ^_ELSE_$ FILE data/nwx/unknown/%m%d_else.wmo The resulting output files are at the maximum limit (a little over 2 GB). I commented-out this entry. I also corrected two entries that were using the replacement strings "(\3:yy)(\4:mm)" because the "4"s should have been "3"s. You'll need to restart your LDM for these changes to take effect. Regards, Steve Emmerson
