Yes that is true for me, at least using the 10g binaries for Linux (not the Ubuntu package). You get this warning everytime you start the engine. You'd probably have to look at your logs to see it. It is also referenced in the installation documentation.
Look guys, MongoDB uses a memory-mapped file. How can it be larger than 2GB on a 32-bit system? There should not need to be "warnings everywhere".
- Saavedro 14y agoI think expecting end-users to know or care about the implementation detail of a memory-mapped file is even sillier than all the other silly expectations floating around this thread.
- jeremyjh 14y agoYou are right I would not expect end-users to know this. I would expect someone who writes articles about DBMS to know this though.
- Cloven 14y agowould you expect someone who writes articles about DBMSes, or comments in a thread about them, to understand that memory mapped file size is (a) not necessarily limited to address space and (b) 64 bit on 90% of the installations of even 32-bit mongo db?
- darkarmani 14y agoWhat do you expect end-users to know about oracle or any kind of database tuning?
- davrosthedalek 14y agoMaybe stupid question, but isn't there mmap64 and mmap2 with which you can map larger files? You are limited to 2 gigs at a time, but that shouldn't be a complete show stopper.
- DannyBee 14y agoHow could it be larger? You could use mmap64.
