There is another limit that might be a factor: it is the total
number of FILE, STDIOFILE, DBFILE, and PIPE entries in a pqact(1)
configuration-file. This limit is defined by the MAXENTRIES macro
in the file pqact/filel.c and is currently hard-coded at 32. If a
data-product arrives that doesn't have a currently active process that
implements the action associated with the data-product, then the process
associated with the least-recently-used action will be terminated
(closing that action's associated file descriptor).
What is the total number of FILE, STDIOFILE, DBFILE, and PIPE entries in
your pqact(1) file?
