We've migrated from ColdFusion MX 6.1 to 8 recently and we're seeing an alarming number of error messages like these: Server Error The server encountered an internal error and was unable to complete your request. JRun Connector Protocol Error. We're running: Cold Fusion 8,0,1,195765 64-Bit Solaris 10 Apache 2.2.10 JRun Connector mod_jrun22.so JDK 1.5.0_16 (we downgraded the JVM as a potential fix) Oracle JDBC drivers 11.1.0.6.0 for JDK 5 (we need Oracle 11g database support) We've spent several days investigating this now. The only patterns seem to be that: -happens a little bit more after a server restart -can return the error very quickly on random pages -but can also return the error on pages that are running big queries and take a long time to run -very inconsistent, we can call the same page multiple times at once - some requests fail, others succeed -we are also seeing a lot of java.io.EOFException errors in our cfserver.log with stack traces of some kind -the logs don't point in any parcticular direction, nor do the JRun Connector errors seem to coincide with any logs entries What we've tried to do to fix this: -Tried the built-in Adobe Oracle database drivers -Tried the JDK 5 version of the Oracle 11.1.0.6.0 database drivers -Downgraded the JVM used by Cold Fusion 8 to JDK 5. -Adjusted the data source connection pools timeouts; turned off Maintain Connections altogether just to see if it made a difference -Adjusted template caching settings -Tweaked the 3 or 4 JRun Connector timeout settings in Apache. Also turned on verbose mode on the JRun Connector to see if that revealed anything. Saw a few suspicious entries, such as: jrApache[init] 127.0.0.1:51800 destroying/closing socket [35] error 0 jrApache[init] jrCloseSocket [35] But these did not parallel all of the JRun connector errors we've been seeing. -Tried connecting to only one database node at a time (we have an Oracle cluster) -Verified our JDBC connection string -Tried reproducing this error under previous Cold Fusion 6.1 production servers and in development environment, but didn't have any luck -Even tried cleaning up the linebreak characters in some of our code after vi complained about "premature end of file" or "premature end of line" - no luck. We're pulling our hair out at this point. The only other thing we've suspected is a firewall or loadbalancer issue causing us to lose connections.
