openssl-0.9.7a-35 errors

[dan]

Hello, all -

I've sent a few emails to the OpenSSL list, and haven't found a whole 
lot of answers to my problem.  Since there are usually some pretty 
clever people around on the fedora-list list, I thought I'd throw a 
message here and see if I could get some feedback.

We're developing an application in-house, written in C++, that uses 
OpenSSL to accept a secured connection from a client (clients are 
currently written in PHP, .NET, and C).  This application is threaded, 
and it works quite well for, well, one thread.  However, as we increase 
the number of threads, we encounter the following error:

6301:error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or 
bad record mac:s3_pkt.c:424:

I'm not as skilled in the ways of gdb as I'd like to be.  The most I've 
done with this is ran an strace on the application, and haven't seen 
anything totally out of the ordinary that I could recognize.

I've linked the app against openssl-0.9.7g, and now we receive the 
following error:

12822:error:140B544E:SSL routines:SSL_GET_NEW_SESSION:ssl session id 
callback failed:ssl_sess.c:220:

Both of these are greek to me - however, I haven't been able to find any 
solid information on these errors, or even what they really mean.  The 
most I've found on the 'net is people complaining about getting these 
errors.

So if anyone has seen these types of errors in the past when developing 
an application, I would greatly appreciate some insight.  I'm just 
grabbing for answers here, and any help would be very good at this point.

Thanks for the time
