Comment (by ttcoder):
It's occuring right now on my desktop, keeping it open in debugger in
case someone wants me to try out a command?
I tried to step.. step.. step.. for a while in debugger, and we never
ever get out of GetAncestor(), I'm always either in node_ref::eq() or in
GeAncestor().
So I would theorize that..
- BOpenHashTable<AncestorHashDefinition>::Lookup() is inlined inside
GetAncestor()
- the infinite loop culprit is inside (i.e. it's not caused by a
continuous stream of B_ENTRY_CREATED messages)
- thus the "root" so to speak, of the stoppage is either [ http://cgit
.haiku-os.org/haiku/tree/src/kits/storage/PathMonitor.cpp#n1394this call]
or [http://cgit.haiku-
os.org/haiku/tree/src/kits/storage/PathMonitor.cpp#n1424 this call] and
the actual guilty party (loop that never exists) would be that one:
http://grok.bikemonkey.org/source/xref/haiku/headers/private/kernel/util/OpenHashTable.h#160
Plausible?
