We have a bunch of middle-tier servers for an application and we're using stunnel to encrypt the traffic between the windows clients and those middle-tier servers. The clients have stunnel.conf files with a large number of services defined and it seems like we're hitting some limit in stunnel. I ran some quick tests and it looks like it's impossible to have more than 64 services defined? If I have a config file with about 100 services defined then everything works fine up until I try to connect to service number 65. When I try to connect to that service then the client just hangs forever (and there's no output in the log file on the client).

We are using version 4.14 but I tested this on 4.15 as well and I am getting the same result there.

Here's a piece of the config file I am using for testing:

"client = yes

; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1

; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log

[blah] accept = 13806 connect = tax187a:13806

[blah1] accept = 13807 connect = tax187a:13806"

Then followed by blah2 - blah100. Things work fine when connect to "blah63" and lower. Anything higher than that cause the stunnel client to just hang.

Thank you in advance, Claus
