Hi Maxim, I cannot help you fix this as I don't have a similar set-up but I can tell you this isn't normal behaviour for NFS. You should not need to tweak anything to get a stable mount at least in my experience.
It sounds like a bug somewhere to me. You could try using the gnu watch command or similar while loop to run an ls of the share from the client to confirm if it hangs after non use or after five minutes regardless of use or non-use. You could also try testing the network connection between the two machines to make sure there is no connectivity or cable problem. You could use the same while loop to run rpcinfo or showmount commands from the client and server to see if it stops working after the same delay. Someone with more knowledge of NFS might suggest some better debugging steps...
