NFS disconnects and weird behavior

[gregfinnegan]

We have an XServe connected to a Solaris box with AFP emulation (Xinet) via an NFS mount (Volumes/Data_Mirror/Ad_01). The XServe is running a web app that needs access to the file system over that mount (think simple content management system – needs to move files around, create new ones, etc.) Every once in a while the web app reports that it’s connection to the NFS mount has disconnected. It’s only for a short period of time and we recover and reconnect, but the logs from the XServe are beyond my ability to figure out what is going one. Any clues would be appreciated.
