Reasons for splitting in decreasing order of importance (in my opinion): 1. To make things easier to understand and maintain (all radar processing in one pqact(1) file, etc.); 2. To take advantage of multiple CPU-s; 3. To reduce file-descriptor reuse. > Thanks, I have been attempting to understand the "twisted > logic" of close_lru() and your statement above helps in that! :) Glad I could help. > thanks again, > daryl > > -- > /** > * Daryl Herzmann > * Assistant Scientist -- Iowa Environmental Mesonet > * http://mesonet.agron.iastate.edu Regards, Steve Emmerson Ticket Details =================== Ticket ID: DBK-582040 Department: Support LDM Priority: Normal Status: Closed
