Description :When trying to create a new package, either the screen does not show the sent package, or there is an error message.
Cause type: Configuration Root Cause: The ulimit value for open files is not set high enough.
The number of open files defined for the user who starts UVMS needs to be increased.
Check what the system limits are for 'open files' using these two commands, while logged in as the user who starts the UVMS: -> ulimit -Hn -> ulimit -n The system limit (-Hn) is the maximum value defined on the system. This can be modified at the OS level in /proc/sys/fs/file-max The user value (-n) might be the same, or lower than the system limit, but should never be larger. This is the value that should be increased.
In the UVMS node settings, check Advanced Settings for the value defined under 'Maximum number of File Descriptors'. By default in v6, this value is set to 8000 and should not be larger than the values shown with the ulimit command. If it is, then the system and user values should be increased to at least 8192. Please note that if the UVMS is started by a non-root user, and a derby backup is being performed, this value should be set to 12288, and the ulimit values may also need to be increased accordingly.
