Hi list,

I successfully set up ocspd with data from 9 CAs as a single point of
revokation data. I left most of the general options in ocspd.conf at their
defaults. After starting the daemon, everything works as expected. A regular
check (a Nagios check script which issues a request via openssl ocsp)
shows whether the daemon is responding and the response contains the
expected data. Now, after increasing usage of ocsp by local applications,
after running for a while the daemon starts adding invalid signatures to its
responses. A restart fixes the problem for another while, which can be days
or just an hour. The Nagios check, running every few minutes, doesn't seem
to trigger the problem, since until now it only occurs at daytimes. The logs
(daemon is always started with -verbose) don't really tell a big story - 
there's
no difference in the entries before, while and after the problem occurs.
Trying to circumvent possible problems with temporary network or ca server
outages, I switched from getting the crl info via HTTP to local files,
regularly pulled by a separate script - but no success. The behaviour is the
same as before. So, I think I need a little help from the list: What can
cause the signatures suddenly become invalid and how to prevent this?
Could this be an obscure bug in ocspd, maybe in conjunction with threading?
