I have an application that open many files for writing very fast, in a way - it can almost be looked as a file system stress test. my application is single threaded, and I noticed the following problem when running a single instance of it: at some point, after opening (and closing) many files for writing, the application fails to open a file for writing. if I sleep for 1 second and try again, it works. my NFS server runs Debian etch 32 bit, with nfs-kernel-server and nfs-common (1:1.0.10-6+etch.1). client is also etch 32. kernel on both is :2.6.18-6-686 #1 SMP Tue Jun 17 21:31:27 UTC 2008 i686 both machines are quad core. I tried to mount with tcp and udp, and tried both sync and async export point. is this a known issue? any known workaround that will not require messing up the application with retry logic?
