[albatross-users] "Broken Pipe" tracebacks...

[Sheila King]

Hello Michael,

Thanks for the response.

Yes, we are running Apache 1.3. Not mod_python, but just usual cgi.

Your comments do seem to corroborate though with what I am seeing.

I doubt we are moving to Apache 2.0 any time soon...

I will pass your remarks on to our Sysadmin, though, for his information...

Thanks again,
