What are the meanings of the various signals in PROCESS_SIGNALS?
I'm trying to track down why one of our clusters went down. In the logs I see messages like this:
2014-05-21 03:24:02.322 Main:0x5b5f2b0 [Main] <INFO> Handling signal: 10
Looking at this page, I see no mention of what signal 10 means.

It could also mean bad memory access, but more likely rotate logs.
Where can I find a list of the meanings of all the possible signals?
What is signal 11, code 1, for example?
From your new thread elsewhere, it sounds like you may have figured this out -- these signals aren't Vertica signals; they are POSIX signals that are being received by Vertica. You can find them documented, for example, here:
http://man7.org/linux/man-pages/man7/signal.7.html
(Scroll down to "Standard signals".)
Signals 10 and 12 are reserved for application-specific purposes; for example, things like log rotation. Signal 11 is SIGSEGV, ie., invalid memory access.
