Incorrect output redirection: When using nohup to execute a command, redirecting the standard error output to /dev/null or elsewhere may result in error messages not being recorded in the log file.
Permission issue: The directory or the file itself of the log may not have write permissions, resulting in an inability to write logs.
Disk space issue: Insufficient disk space where the log files are located may prevent logging.
File descriptor limit: The system restricts the number of file descriptors that each process can open, exceeding this limit may result in the inability to write to logs.
The system log service is not running: If the system log service is not started or configured incorrectly, it may result in the inability to write logs.
If the log file is deleted or moved, it could result in the inability to write to the log.
The log file is being used by another process: If another process is using the log file, it may cause issues with writing to the log.
