Dear Mark, I'm not entirely familiar with how the file descriptors are being allocated in cfexecd. But I'll tell you roughly what is done in the cfagent.conf. I can't post the exact configuration for security reasons.
The major work that I configure to run daily is copying a tree of files from a master running cfservd (Hr06.Min00_05 - UTC). That is not very large in size in terms of MB but there is indeed a large volume of files in there each pretty small in size. I also have some tasks configured to run to check existence of some important symlinks and check whether some aged files exist in certain preset locations and critical processes running (starting if not found). That is run every 30 minutes. I will also pull /var/cfengine/inputs from the master every 30 minutes, although the config have been pretty much unchanged for a few months already. That is a small tree with a small no. of files. FYI, I got the first MAXFD error log about 5 hours after I restarted cfexecd.
