[stunnel-users] "STACK_RESERVE is too high" after every connect

[Rob Munsch]

Hello.  I've recently gone on a self-inflicted crash course on openssl 
and seem to have gotten a centralized logging system going, logging to 
MySQL.  I'm seeing everything i'd expect to see, but with an extra bit:  
what is STACK_RESERVE, and why is it too high?

Some context, mildly sanitized:

|Mar  9 18:33:34 isis stunnel: LOG5[24810:6]: syslog-ng connected from x.x.x.x:44032|

|Mar  9 18:33:34 isis stunnel: LOG5[24810:6]: VERIFY OK: depth=1, /C=US/ST=Pennsylvania/L=Philadelphia/O=Solutions for Progress/CN=blah.com/emailAddress=blah at blah|

|Mar  9 18:33:34 isis stunnel: LOG5[24810:6]: VERIFY OK: depth=0, /C=US/ST=Pennsylvania/O=Solutions for Progress/OU=IT/CN=IT/emailAddress=blah at blah|

|Mar  9 20:39:02 isis stunnel: LOG5[24810:6]: Connection closed: 0 bytes sent to SSL, 2891 bytes sent to socket|

|Mar  9 20:39:02 isis stunnel: LOG3[24810:6]: STACK_RESERVE is too high|


this is daemon.log on the server machine (isis).  Messages from the 
remote host are going to MySQL successfully.  But at the end of every 
apparently-successful transaction, there's this stack complaint.
Can't find anything in the archives or via Google for "stunnel 
stack_reserve," which i found really odd, which is why i'm here...

Version output:
stunnel 4.14 on i686-pc-linux-gnu UCONTEXT+POLL+IPv4 with OpenSSL 0.9.7g 
11 Apr 2005

Thanks!
