Bug ID: 238675
Summary: POSIX timer (timer_create) limit is too low (32)
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: greg@unrelenting.technology
epoll-shim https://github.com/jiixyj/epoll-shim implements the Linux timerfd
API via threads and POSIX timers.
libwayland-server allocates a timerfd per client.
sys/timers.h defines TIMER_MAX as 32.
As a result.. you can only run 32 Wayland clients! :D And I've started hitting
this limit in practice (especially with many WebKit processes).
Looks like on Linux, the limit of timers is RLIMIT_SIGPENDING which is 16382 by
default:

Our limit should be raised.
