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.
