Problem ITO agents stop processing due to too many files being open.
Description If the permanent file, LASTUUID.PUB.HPNCS has not been created, NCS
creates a temporary one, which it does not close. Over a period of time, it
tries to re-creates this file many times. The result is that the number of
open file descriptors increases, and the system table used to administrate
open files is overloaded. It is then not possible to open any new files.
Solution Check that the file LASTUUID.PUB.HPNCS exists:
listf LASTUUID.PUB.HPNCS
If the file does not exist, stop all ITO agents, working as user
AGENT.OVOPC:
opcagt.bin -kill
Create a new file as user MGR.HPNCS:
hello agent.ovopc
opcagt.bin -kill
hello mgr.hpncs
build lastuuid.pub.hpncs
hello agent.ovopc
opcagt.bin -start
