Hello Mark,
Thank you for reporting this. Two things: If you can, please install NCO 4.4.4. We fixed numerous memory issues in the 4.4.x series. I doubt this issue will occur in 4.4.4 (if it does then send me the file and command so I can attempt to reproduce). Second, often these memory free errors occur after the output file has been written. So you might check to see if the output file looks fine. Then you can keep using the versions you have installed until you have time to upgrade.
Good luck,
cz

Hello,
system admin compiled with intel nco 4.3.8
and with gnu nco 4.4.3
In both cases there are some memory errors.
Could you help?
Thanks,
Mark
