It is required that Opertating System Administrator the amount of open files allow by OS to the users (file-descriptor-count).
To see the settings for a user, as root issue the following commands:
su - <user that Run Nimsoft Hub daemons>
The default setting for this is usually 1024. If more is needed for a specific user than as root modify it in the /etc/security/limits.conf file:
@user -nofile 2048
Will set the maximum open files for the specific "user" to 2048 files.
To do a system wide increase for all users as root edit the /etc/security/limits.conf file and add the following:
* - nofile 2048
This sets the maximum open files for ALL users to 2048 files. These settings will require a reboot to become active.
After performing the change verify that "ulimit -n" for the corresponding used was increased .
Note 1: Keep in mind that this way of configure Ulimit may variate depending the Unix/Linux version. Please adjust this setting with the Operating System Administrator.
Note 2: The command "lsof | wc -l " could help you determined the amount of file-descriptor-count required.
