Good afternoon!
We have a new AMD EPYC machine with 144 cores (upgraded from 8 core
machine) running Windows 10 Enterprise, with a mixture of native Win32
apps+Cygwin.
But the Cygwin apps cause trouble, as PID numbers get re-used too
fast. We churn through ~~6912000 child processes EVERY HOUR, which now
causes major problems with PID wraparounds in scripts and perl.
1. How can I increase the value at which pid-wraparound will happen?
2. How can I test for Cygwins max PID value? Cygwin does not have
/proc/sys/kernel/pid_max
winsup/cygwin/pinfo.cc:create_cygwin_pid() 65535 but defined as int/32
- perhaps possible for 3.6?
