Zabbix relies heavily on shared memory configuration. If your CacheSize , HistoryCacheSize , or HistoryIndexCacheSize parameters are too low, processes block each other while waiting for memory allocation, leading to dropped socket connections. 4.

If the preprocessing service stops (due to memory leaks or bugs in specific versions like 6.0 or 7.0), other processes trying to send data to it will fail with this error.

Tune shared_buffers , work_mem , and look into setting up Zabbix database partitioning to keep tables small and performant.
