Technote (troubleshooting)


Problem

Your Lotus Domino 8.5.2 server crashes with the following error message:

PANIC: AccessAllProtected() error *** (this number can be 1B1 or 107 or other) from MapSharedRegion on pool *** (this number can be any 3 digit pool number) of *** (total number of) pools.

Symptom

The following crash stacks are most likely to be seen:

1. on AIX

OSRunExternalScript
OSFaultCleanupExt
OSFaultCleanup
Panic
AccessAllProtected()
AccessAll
ProcessGlobalEvent
OSProcessShouldQuit()
WaitOnNativeSemaphore
OSWaitEvent
Wait__7HTEventFUl
ThreadMain__14HTWorkerThreadFv
HTThreadBeginProc


2. on Windows

AccessAllProtected
AccessAll
ProcessGlobalEvent
OSProcessShouldQuit
OSWaitEvent
HTEvent::Wait
HTWorkerThread::ThreadMain

NSD also reports: "Process memory for nHTTP (PID:****) is near the OS limit".

Cause

HTTP memory allocation has an incorrect setting in the notes.ini on the server: HTTPJVMMaxHeapSize=1024M

In most cases you will see the following:

1. The crash stacks match the above.
2. The HTTP process memory is near the OS limit in the NSD.
3. HTTPJVMMaxHeapSize=1024M is set above 256.


Environment

This problem has been seen in Domino 8.5.2 on AIX and Windows.

Resolving the problem

HTTPJVMMaxHeapSize should be set at either the new default for 852 > 64M HTTPJVMMaxHeapSize=64M.

This can also be set to HTTPJVMMaxHeapSize=256M as per technote 1377202 What is the HTTPJVMMaxHeapSize notes.ini parameter in Domino 8.5 and what should it be set to?


Another option is to delete the ini parameters HTTPJVMHeapSize and HTTPJVMHeapSizeSet from the notes.ini and restart the server. These will be recreated. Check that they are set to the defaults after the restart:

HTTPJVMMaxHeapSizeSet=1
HTTPJVMMaxHeapSize=64M

This issue was reported to Quality Engineering as SPR# RCOR8BJMME.
