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 ?
Si se usa OpenJDK, requiere la instalación de paquetes debuginfo.
En Centos esto funciona con - sudo debuginfo-install java-1.8.0-openjdk
- o sudo yum install java-1.8.0-openjdk-debuginfo.x86_64
Consulte - https://bugzilla.redhat.com/show_bug.cgi?id=1010786#c15 - amazon linux - instale openjdk-debuginfo?
