Which operating system does this occur on? You could try a newer version of Agent, but you may not be able to find a 6.19.x.x that's higher. That version of code is no longer supported.
Nothing is supported from thr list of technology mentioned in the thread.
OS: RHEL 3.5, EOSL by Redhat
Array: CX300 and FLARE 02.19.300.5.034, EOSL by EMC (Actually, entire CX Family)
Navi Agent mentioned in there may bs the only thing available to download support portal, I doubt it though.
