@dmitripivkine @hzongaro another problem which seems recently introduced, and is repeatable. Unfortunately we're not getting diagnostic upload on AIX, but only on Linux PPC (automation/issues/116).

dmitripivkine · 2024-11-11T22:50:14Z

I will check what I can see, but this one is JIT related most likely. The crash occur in the GC End Hook event.

vij-singh · 2024-11-12T13:06:46Z

@zl-wang FYI

IBMJimmyk · 2024-11-13T20:38:39Z

I tried looking at the core file for http://vmfarm.rtp.raleigh.ibm.com/job_output.php?id=95773976 (internal link)

https://github.com/eclipse-openj9/openj9-omr/blob/3da49aa3aaed9217fb02d5ab3d069aa7142f89ba/compiler/runtime/OMRCodeCache.cpp#L711-L716

What happens is startPC there returns -3 which is treated as a real start PC and leads to a crash.

The J9Method passed into the startPC looks like this:

(kca) j9m 0xb19b111c
Method   {ClassPath/Name.MethodName}: {javax/crypto/EncryptedPrivateKeyInfo.<init>}
                           Signature: (Ljava/lang/String;[B)V

                       Constant Pool: 0xb19b0bf0 (98 entries)

openj9/runtime/compiler/runtime/Trampoline.cpp

Line 178 in 4b8e6ef

void ppcCreateMethodTrampoline(void *trampPtr, void *startPC, void *method)

The trampPtr passed into ppcCreateMethodTrampoline looks to be 0x9dffa280.

The code starting from 0x9dffa280 looks like this:

EncryptedPrivateKeyInfo.<init> was compiled at warm but looks like it was invalidated.

a reasonable fix is: at the point to re-create the permanent trampoline, testing newPC. if it is not compiled (meaning trials of compilation all failed), recreate with oldPC (at oldPC location, it is already patched to go back to interpreter).

zl-wang · 2024-11-13T20:56:40Z

this should happen very very rarely ... never run into this situation before.

just curious why vmState=0x00020012 is not recognized as valid vmState. It is defined in the code obviously:

#define OMRVMSTATE_GC_COLLECTOR_CONCURRENTGC (J9VMSTATE_GC | 0x0012)

pshipton · 2024-11-15T20:14:59Z

The JIT doesn't print GC states. I shouldn't have tried to look it up like I do for JIT states.

I created a PR for a fix here:
eclipse-omr/omr#7550

I was able to create a small test case to reproduce the failure. The verbose log output looks like this:

+ (warm) RedirectTrampoline.callB(I)I @ 00007DB37A8700F8-00007DB37A8701C4 OrdinaryMethod - Q_SZ=1 Q_SZI=1 QW=13 j9m=00007DB398890FA8 bcsz=40 sync compThreadID=0 CpuLoad=5%(0%avg) JvmCpu=0%

callB is compiled.
callA is compiled. stressTrampolines is set so it uses a trampoline to call callB.
callB is re-compiled at profiled very-hot.
callB is attempted to be re-compiled at scorching but intentionally fails.
callB is attempted to be re-compiled at warm but intentionally fails and no further attempts will be made.

After that, I get a global GC to happen which triggers syncTempTrampolines and without my fix a crash occurs. With my fix, everything is okay.

This is not expected to fix #20546 but I am moving on to looking at that one next since the problem looks similar.
