java exception jmap

java - Excepción al tomar un heapdump utilizando JMAP



exception (2)

Estaba viendo el mismo error porque mi ruta a jmap no era la misma que la ruta al proceso java (es decir, a dos versiones diferentes).

Ejecutar jmap con la ruta completa a mi JDK lo resolvió.

Obtengo la siguiente excepción cuando tomo un heapdump usando

jmap -F -dump: format = b, file = / tmp / heapdump / before.hprof 10737

Attaching to process ID 10737, please wait...

Alguien sabe como resolver esto ?
