I've been working on this for a few weeks but now I'm kind of stuck.
I currently have two docker containers. Both of them are running the following java version:
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
I'd need to be able to make Container1 get a jmap dump from Container2 and dump it locally.
I've been using strace on Container1, and I can attach the java process running on #2, but when I use jmap, I get the following error:
futex(0x7f6f4c80c9d0, FUTEX_WAIT, 52, NULL51: Unable to open socket file: target process not responding or HotSpot VM not loaded.
I know the signal GETS to Container2 since I can end processes just fine, but what else should I be looking out for?
Thanks!
