Not that I mind, ingesting > NOAAPort and running this script is all the system does anyway. The EXEC-ed program will be executed the same number of times regardless of whether the "-wait" option is used or not -- so the computer will do the same amount of work. Whether it will do this work slower if the "-wait" option is used is hard to say and is usually determined empirically. > >Along those lines, what is the limit on the number of child process a > >user may have?

This means that the LDM user is limited to 1024 processes -- totaled over all sessions. > >Is there anything relevant in the LDM logfile from the pqact(1) process? > > > Nope, nice and clean (which is part of the confusion). Hmm... The pqact(1) program will log a message if it can't EXEC a program for any reason. Therefore, it can't be hitting the process-limit. Let me know the results of using the "-wait" option. > Thanks for the help! > > Steven Regards, Steve Emmerson
