Re: Making LOG EVENT thread-safe

Chip's right about server-side code not needing network bandwidth. I was jumbling a few of my stories unclearly. Yes, we're starting with server-side only process getting logged, but that will change. Once you want to keep error, access, and event logs and tie them together, it's nice to be able

Making LOG EVENT thread-safe

I finally got around to checking, and LOG EVENT is not a thread-safe command. Pity! It would be very handy if this command were usable from a preemptive process as it would give us a great way to stream log data out to the system for collection by an "agentless" (cough-cough) tool like Loggly.
