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@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@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!
