My node was dying repeatedly because of running out of file descriptors. It turned out to be down to NativeFSDir having too many files open. In the grand Freenet tradition of treating the symptoms, I have implemented a pooled RandomAccessFile system, so that we only have the LRU <n> files open at any given time, the others are opened when needed. Linux and most unixes have a default maximum FDs including sockets of 1024, so I will set the default to 256. But what should it be set to for various forms of Windoze? Win95 has a 50 socket limit and Win98 has a 100 socket limit IIRC, but I don't know whether that includes file handles too... Windows NT/2K/XP apparently have no limit by default, so I can set it to infinite. According to some win32 api docs I read ages ago. More recent information: "Since stdio level functions, such as fopen, are built on top of the lowio functions, the maximum of 2,048 is a hard upper limit for the number of simultaneously open files accessed through the C run-time library." http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_crt__setmaxstdio.asp
So I will set a limit of 1024 for unrecognized Windowses. MacOS/X has a 256 fd limit per user by default, we set maxNodeConnections by default to 128, so I will set maxNodeFilesOpen to 64. -- Matthew J Toseland - [EMAIL PROTECTED] Freenet Project Official Codemonkey - http://freenetproject.org/ ICTHUS - Nothing is impossible.
