Subject: Domino hungs on system databases being locked
Feedback Type: Problem
Product Area: Domino Server
Technical Area: Crash
Platform: ALL
Release: 8.5.2
Reproducible: Always
Hi
The problem is that administration processes such as compacting databases produce dead locks. For example compact is scheduled in program documents to compact databases . When compact starts, server hungs because other processes want to write to log.nsf and are not allowed because of dead locks. Server does not respond to client requests neither to console commands.
Killing domino and restarting it from the scratch solves problem until program document starts compact again :(

Clearing DBIID F1825326 for DB D:\Lotus\Domino\Data\log.nsf
LkMgr BEGIN Long Held Lock Dump ------------------
Lock(Mode=X * LockID(DB DB=D:\Lotus\Domino\Data\log.nsf)) Waiters countNonIntentLocks = 2 countIntentLocks = 0, queuLength = 45
Req(Status=Granted Mode=X Class=Manual Nest=0 Cnt=1
Tran=0 Func=N/A [122C:0004-0A34])
Thus queuLength is growing, server does not respond to clients neither to console commands.
Other databases such as admin4.nsf and other are also affected:
LkMgr BEGIN Long Held Lock Dump ------------------
Lock(Mode=X * LockID(DB DB=D:\Lotus\Domino\Data\admin4.nsf)) Waiters countNonIntentLocks = 2 countIntentLocks = 0, queuLength = 3
Req(Status=Granted Mode=X Class=Manual Nest=0 Cnt=2
Tran=0 Func=N/A [0D8C:0004-0E60])
