Public bug reported: In my newly upgraded (from 15.04) Ubuntu 15.10 system, after I've been logged in for a while I can no longer open new windows and instead get a "Maximum number of clients reached" error.
This did not happen in 15.04. I ran "lsof" on the X server and did not see an excessive number of open file descriptors. I ran it again on a newly restarted X server and the number of open file descriptors looked about the same. I also ran "xlsclients" when the X server was reporting "Maximum number of clients reached" and the list of clients looked correct and reasonable (and there were less than 30 of them). I am happy to collect any additional logs or debugging information to help track this down. I don't know where to look further.
