Hi Kamen, I can't see anything wrong with your netCDF calls. I don't think the messages you are seeing are related to netCDF. Here's a similar bug that was reported and tracked down to setting an environment related to debugging a running Firefox instance: http://lists.debian.org/debian-glibc/2008/06/msg00103.html It may help to look at the report and resolution of the above problem to see if you are doing anything related to this, such as setting the environment variable "MOZ_LAUNCHED_CHILD" ... --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: LDE-989755 Department: Support netCDF Priority: Normal Status: Closed
