Assertion failed in PGMAllPool.cpp(1517) int pgmPoolMonitorInsert(PGMPOOL*, PGMPOOLPAGE*) rc=-1701

A 1.5GB RHEL5 guest crashes on a 4GB Host using Ubuntu Intrepid (Kernel 2.6.27-7) during an Oracle installation in the guest machine.

The location of the crash is in pgmPoolMonitorInsert() and the errorcode is -1701(VERR_MM_HYPER_NO_MEMORY) which means that a call to MMHyperAlloc() was not able to allocate any memory although enough cache and swap is available.

There has been some discussion on the issue in the virtualbox-forum in that link: ​http://forums.virtualbox.org/viewtopic.php?t=10710

The assertion which failed is located here in line 1517 of PGMAllPool.cpp:

   1509         rc = PGMHandlerPhysicalRegisterEx(pVM, PGMPHYSHANDLERTYPE_PHYSICAL_WRITE,
   1510                                           GCPhysPage, GCPhysPage + (PAGE_SIZE - 1),
   1511                                           pPool->pfnAccessHandlerR3, MMHyperCCToR3(pVM, pPage),
   1512                                           pPool->pfnAccessHandlerR0, MMHyperCCToR0(pVM, pPage),
   1513                                           pPool->pfnAccessHandlerGC, MMHyperCCToRC(pVM, pPage),
   1514                                           pPool->pszAccessHandler);
   1515         /** @todo we should probably deal with out-of-memory conditions here, but for now increasing
   1516          * the heap size should suffice. */
   1517         AssertFatalRC(rc);

which means that "rc" is set by either a call to MMHyperAlloc() or a call to pgmHandlerPhysicalSetRamFlagsAndFlushShadowPTs() in PGMAllHandler.cpp

The error occurs on the guest regardless of the size. I tried 900M, 1024M and 1536M.

Very likely this ticket might be a duplicate entry to ​http://www.virtualbox.org/ticket/1629 but here is no USB-logic involved at all.

Logfile of the crash mentioned in the forum.

Further investigation gave that this issue is in 1.6.6 as well as in 2.0.2. After a purge of the virtualbox-2.0 Package I installed the virtualbox-Package 1.6.6 and retried the installation resulting in a GURU-Meditation of the Guest-Machine. This issue is pretty reproducible on this machine.

The errorcode is the same as in 2.0.2 - just the position in the sourcecode is some other.

Results from different memory settings of the guest machine:

• 1536M-RAM Guest: Guest crashes during Installation of Oracle 10.2.0.1/32
  
• 1024M-RAM Guest: Guest crashes during Installation of Oracle 10.2.0.1/32
  
• 896M-RAM Guest: Installation of Oracle 10.2.0.1 works (despite the warning of low RAM) but crashes during the 10.2.0.4 patch procedure during "dbua" (which is quite ressource intensive).
  
• 786M-RAM Guest: Installation of Oracle 10.2.0.1 works (despite the warning of low RAM) and the 10.2.0.4 patch was fine.
  

The host in question has always been the same and the guest has no USB support at all.

Error exists still in Virtualbox 2.0.4 - SLES10SP2-Guest using 1024M RAM

[vondralbra]

Not reproducible any more in 3.0.4 using 1536M RAM and SLES10SP2
