AppMon: 6.0, 6.1 (Windows only)


The server or collectors are constantly restarting every few minutes. The launcher log files contain the log message

warning [native] Error on reading from socket 50000: [720997] Overlapped I/O operation is in progress.

and are then filled up by stack traces on every restart.


Replace the launcher binaries with the fixed versions:

Root Cause

The native launcher, which starts the server or collector JVM, cannot open a network port for watchdog communication, so the watchdog is restarting the Java application (AppMon server or collector) after timing out.
