LINUX-106logrotate recreates the file but resets the ACL and the application loses write access after midnightThe service is healthy all day, yet every night it fails because the replacement log file does not preserve the same access model as the original.LinuxIntermediate15 minProLINUX-375A log rotation policy is correct while a filebeat or rsyslog harvester keeps the deleted descriptor open and disk usage never falls during a staged decommissionThe rotated files are gone from the directory and still present on disk. The service still works through the primary path, but one dependency only fails when the old component is finally drained away.LinuxIntermediate16 minProLINUX-168A telemetry agent writes checkpoints to the small root disk instead of the intended data mount during a failover rehearsalLogs keep flowing while state files quietly consume the partition the system needs most. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.LinuxIntermediate16 minProLINUX-107A tuned profile reapplies IRQ balancing after reboot and network latency returns on the database nodeManual tuning helped temporarily, but the performance regression comes back because the system profile manager writes its own preferred state at boot.LinuxIntermediate16 minProLINUX-228A journal vacuum policy frees one filesystem while a coredump directory on another keeps growing unchecked during a failover rehearsalLogs look healthy and the diagnostic path that really consumes space was outside the cleanup policy. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.LinuxIntermediate17 minProLINUX-312A journald retention policy frees local logs while remote-forward queue spillover still fills the spool filesystem during collector outages during a failover rehearsalLog retention seems tuned and the buffering path for remote resilience is where storage actually disappears. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.LinuxIntermediate17 minProLINUX-495A log rotation policy is correct (Resource Exhaustion)A log rotation policy is correct (Resource Exhaustion) focuses on linux-performance-and-observability and asks the reader to isolate Resource Exhaustion. 실무에서는 linux-performance-and-observability 문제를 볼 때 서비스 로그만 보지 말고 inode, 파일시스템 여유, 포트 점유, systemd 상태, 최근 패키지 변경까지 같이 확인해야 원인을...LinuxIntermediate18 minProLINUX-494A log rotation policy is correct (Resource Exhaustion)A log rotation policy is correct (Resource Exhaustion) focuses on linux-performance-and-observability and asks the reader to isolate Resource Exhaustion. 실무에서는 linux-performance-and-observability 문제를 볼 때 서비스 로그만 보지 말고 inode, 파일시스템 여유, 포트 점유, systemd 상태, 최근 패키지 변경까지 같이 확인해야 원인을...LinuxIntermediate19 minProLINUX-554A log rotation policy is correct (Resource Exhaustion)A log rotation policy is correct (Resource Exhaustion) focuses on linux-performance-and-observability and asks the reader to isolate Resource Exhaustion. 실무에서는 linux-performance-and-observability 문제를 볼 때 서비스 로그만 보지 말고 inode, 파일시스템 여유, 포트 점유, systemd 상태, 최근 패키지 변경까지 같이 확인해야 원인을...LinuxIntermediate20 minProLINUX-611A log rotation policy is correct (Resource Exhaustion)A log rotation policy is correct (Resource Exhaustion) focuses on linux-performance-and-observability and asks the reader to isolate Resource Exhaustion. 실무에서는 linux-performance-and-observability 문제를 볼 때 서비스 로그만 보지 말고 inode, 파일시스템 여유, 포트 점유, systemd 상태, 최근 패키지 변경까지 같이 확인해야 원인을...LinuxIntermediate20 minPro
