Hi,
We have CUI(Character user interface) based application running on our AIX4.3 box. To keep the application stable every day, we have a regular scheduled application reboot (not AIX reboot) at midnight.
The application restart process executes the sync command and then uses some native application level commands to close any open databases, kill the background app processes, bring down MQ channels and starts everything backup. However, for the past two days, we are having issues with this process. The sync command gets stuck and the system hangs there for a while. We called the unix administrators and they had to manually reboot the AIX box.
Does any one of the reason when sync get stuck? Is there any log file for the sync process that I can look at? I tried to find it in the system, but to no avail.
Please help.
Thanks,
Balaji.
