Hey folks --
Can anyone tell me where the max number of clients is configured in 4.21? I'm running okay for a while, but then I end up with repeated messages as below in the logs:

------------- Config below -----------------
ulimit unlimited
Hi Chris,
At least for my bash, 'ulimit' without any options returns the limit for the file size. To get the limit for the number of files, I have to type 'ulimit -n' or 'ulimit -a' (and get 1024).
On our linux box, stunnel logs the following on startup:
FD_SETSIZE=1024, file ulimit=1024 -> 500 clients allowed
which seems to match your observation.
I vaguely remember the limit for the number of open files on linux can be adjusted somewhere in the /proc file system, but I don't really know.
In any case, the limit you are hitting is set by the operating system.
