Ah, silly me! My eye missed it every other time I read this thread -
seems that just about everyone above who was reporting crashing
AOLservers also said they were using OpenSSL
0.9.6x.
Bruno didn't say exactly what version he was using, but the Red Hat
link he gave seems to show that the latest updated packages for all
consumer Red Hat distributions prior to Red Hat 9.0 are using
an OpenSSL older than 0.9.7x. Which is suspicious, as it's
possible that RH backported the RSA blinding security patch but
not the thread-safety fix.
So the fix should be simple, just upgrade to 0.9.7b. Note that Scott
Goodwin
says
that nsopenssl 2.1a requires OpenSSL 0.9.7x or later anyway.
