Have you experienced critical failures or issues in a work environment that led to system crashes?

Yes, in my practice there have been cases where critical failures occurred in the working environment, leading to system crashes. In such situations, it is important to quickly identify the cause — for example, memory leaks, deadlocks, data processing errors — and promptly take measures: restarting services, fixing code, adding monitoring and alerting. It is also useful to have a logging and tracing system to analyze incidents and prevent their recurrence.
