LINUX-030Process limit reached by short-lived workers instead of main appThe service owner blames the main process, but the true limit is exhausted by a burst of helper processes spawned underneath.LinuxIntermediate19 minFreeLINUX-032Systemd service starts manually but fails on boot without network-online targetThe unit runs when started interactively, yet boot-time startup fails because dependency ordering assumes the network is ready earlier than it actually is.LinuxIntermediate19 minFreeLINUX-012A tmp directory cleanup policy that intermittently breaks only upload processingA tmp directory cleanup policy that intermittently breaks only upload... is a hands-on troubleshooting drill. A situation where a batch cleanup task collides with the application's temp files, breaking only a specific feature. Azure Linux Storage and Filesystems needs to be ch...LinuxIntermediate20 minFreeLINUX-074Boot stalls on a dead NFS mountThe host itself is healthy, but boot takes far too long because a remote mount is treated like a local dependency and blocks the sequence.LinuxBeginner13 minFreeLINUX-060Package manager lock remains after a dead process and blocks patch automationThe scheduled patch job says another package process is running, but the real blocker is an abandoned lock or stale transaction state from an older failure.LinuxBeginner14 minFreeLINUX-038Sudoers drop-in order silently reintroduces password promptsThe main sudoers file looks correct, but a later drop-in overrides the intended NOPASSWD rule and breaks the automation path.LinuxBeginner14 minFreeLINUX-069Unattended patch job failsPackage metadata is reachable, but only one channel refuses updates because its signing key aged out and the automation never refreshed the trust path.LinuxBeginner14 minFreeCICD-117Webhook filters only trigger on merge queue branches and hotfix tags skip the production deployment workflow entirelyNormal merges deploy correctly, but emergency releases never enter the deploy pipeline because the event filter no longer matches tag-based flows.CI/CDIntermediate14 minFreeCICD-124A monorepo path filter skips the shared library hotfix, and only services outside the touched directory keep shipping the vulnerable packageThe PR diff looks narrow, but the actual dependency graph is wider than the changed path filter acknowledges.CI/CDIntermediate15 minFreeCICD-114ChatOps release command targets productionOperators trigger the same command they always used, but the command router now resolves to production due to a renamed default target.CI/CDIntermediate15 minFreeCICD-130The package registry enforces immutable tags, and a retry step keeps pointing releases at an older artifact that happened to claim the same version firstAutomation retries help reliability elsewhere, but here they turn a transient publish issue into a stale release artifact.CI/CDIntermediate15 minFreeCICD-119Build jobs pin Node 20 while deploy jobs still render assets on Node 18 and checksum validation fails at release timeThe same commit produces different asset bundles depending on which stage builds them because the toolchain version is not truly centralized.CI/CDIntermediate16 minFreeCICD-106Matrix test sharding skips the failing packageThe aggregate workflow passes, but one package never runs in CI after a sharding rule change silently excludes it from every matrix segment.CI/CDIntermediate16 minFreeLINUX-004An open log-file problem where space is not freed even after logrotate runsCovers a common operational trap where swapping the log file without restarting the service still does not free space.LinuxBeginner18 minFreeLINUX-059Service keeps old environment valuesThe operator updates the environment file on disk, but the running service still behaves as before because the effective process state was never reloaded or restarted correctly.LinuxBeginner13 minFreeLINUX-027Tar backup excludes filesThe backup command seems valid, but quoting and wildcard expansion remove important files before archiving starts.LinuxBeginner13 minFreeLINUX-055Monthly cron cleanup runs in UTC and deletes the wrong day of dataThe script is valid, but the job executes on the system default timezone instead of the operator assumption and trims data outside the intended maintenance window.LinuxBeginner14 minFreeLINUX-020The env-var file was edited, but an already-running process does not know the valueThe env-var file was edited, but an already-running process does not know the... is a hands-on troubleshooting drill.
