From: "J. Bruce Fields" <bfields@xxxxxxxxxx> Current client and server defaults can limit NFSv4.1+ mounts to as few as 4 per gigabytes of server RAM, and people have been running into the limit on upgrading the protocol version from 4.0 to 4.1. Bump the limit. Also return smaller ca_maxrequests as the limit approaches instead of waiting till we have to fail CREATE_SESSION completely. A few years ago Trond also posted some patches to dynamically resize existing sessions as limits approach--I'll revisit those at some point too. The numbers chosen here are honestly still a little arbitrary, and we may tweak them again if we see more problems. --b. J.
