Looking at this page, I see no mention of what signal 10 means.
What are the meanings of the various signals in PROCESS_SIGNALS?

+1I'm trying to track down why one of our clusters went down. In the logs I see messages like this:
signal 10 is used to signal vertica to rotate logs.
See if a new log is started for the vertica.log soon after signal 10.
It could also mean bad memory access, but more likely rotate logs.

+1OK, sounds good.
Where can I find a list of the meanings of all the possible signals?
What is signal 11, code 1, for example?

+2Hi Nicholas,
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.

+1Yep, I eventually figured it out. 
I suggest updating the documentation on PROCESS_SIGNALS to indicate as much, because it's not obvious.

+1I also think this should be documented !
