When using eBPF as a telemetry source, the number of file descriptors required is directly proportional to the number of CPUs. As a result, on endpoints with a large number of CPUs, file descriptors may run out.
The sensor will restart, and there will be a message in the
cf_system_log.csv file that states
No file descriptors available.
To fix this, raise the file ulimit value on the affected endpoint(s). For more information, please read Increase set open file limits.
