I'm working on upgrading from stunnel 4.04 to the 4.15 to utilize the per port specification of a certificate. On my initial testing, I ran with only a few ports, specified the different certs, and, everything seems to work fine. I'm ran into a problem, though, when trying to use the same config file in regards to the number of configured ports. I have 104 inbound ports setup, and, when it hits the 69th configured port, I get the following message for this, and every port that follows:
s_poll_add failed for FD=69: too many file descriptors
I checked the code, and, this is what I found:
#define MAX_FD 64
I didn't find a relation to any configurable options, so I made a change to this parameter in the code, recompiled, and, I was able to start up all of my listens without error.
I just wanted to pass this along, and, if it does tie into a configurable parameter, my apologies for not finding it....if someone knows it, please pass that on. Thanks!
