Description:

Executors started dying on one node with unknown reason. Other nodes are not affected
According to Jenkins UI, all executors (excepting ones with a running build) continuously die and restore
- No error info even on the FINEST log level
- Executor::causeOfDeath field is null when I open the death descriptor
- causeOfDeath page is accessible, hence Executor::isAlive() returns false
Probably, a node user decreased the number of executors (to be checked)
WARNING: Caught exception evaluating: h.printThrowable(it.causeOfDeath) in /computer/XXXX/executors/4/causeOfDeath. Reason: java.lang.NullPointerException
java.lang.NullPointerException
