Guilty commit : https://github.com/reactos/reactos/commit/b445005c7086ef76a0acefc022878d47ada1487c by zefklop 

This guilty commit is "[NTOS:MM] Get rid of MmRosFlushVirtualMemory" which seems to affect MmFlushVirtualMemory (see log below)

Maybe Miranda is checking return code of NtFlushVirtualMemory which is then returning STATUS_NOT_IMPLEMENTED after this change due to https://git.reactos.org/?p=reactos.git;a=blob;f=ntoskrnl/mm/ARM3/virtual.c;hb=5db69da46b09b98cf382864cfc4f9967d8d6dbad#l4119 

This "hack" PATCH fixes the problem until MmFlushVirtualMemory is properly implemented (ntoskrnl/mm/ARM3/virtual.c) :

Miranda 0.10.21 from RAPPS

• Start Miranda
• Create account
• Start moving window around the snap area (right border of desktop). If snaps then unsnap / re-snap.
• After a few (3-5) seconds and/or a few attemps "Database Panic" error occurs. Need to delete Miranda user settings to restart from a fresh account (that immediately fails on the same condition afterwards)
• Regression as not happening on  0.4.13-RC-53-g4f628f6 in CORE-16763
