[resending - with more current address for trond] Hi Trond et al. we have a customer who reports getting the message: [10879512.275305] NFSv4 callback: too many open connections, consider increasing the number of threads. [10879512.275315] NFSv4 callback: too many open connections, consider increasing the number of threads. [10879517.276133] __ratelimit: 133011 callbacks suppressed Of course you cannot increase the number of threads handling callbacks. The patch below will get rid of the message - which is presumably mostly just noise - or possibly change it to NFSv4 callback: too many open connections, consider increasing the max number of connections if the number of connections gets too high. This isn't much good as this patch doesn't allow the max number to be increased. Do we want to make the max number of callback connections configurable, or should we find a way to silence that message. (For lockd that message is valid as there is a sysctl to change the max number of connections for lockd). Thanks, NeilBrown
