We have a need to increase the kernel pid_max. Right now it's at the
default 32768. The maximum allowable we can increase to is 99,999 due to
3rd party vendor limitations. When we increased it to that value this
weekend, we noticed that even though next pid increased sequentially, the
range 32769-65535 was explicitly skipped.
I note that the range 32769-65535 would be the negative numbers in a
signed 2 byte int. This indicates to me that maybe there is some sort of
design/legacy issue forcing this behaviour.
Because we can only increase to 99,9999, not having access to the above
range has limited our available pids by 1/3. Could anyone point me to some
sort of documentation explaining this logic?
Thanks for your help,
