[Citadel Support] Re: Thunderbird does not update citadel?

Also, it's possible that your Citadel server process is crashing on 
something, and automatically restarting so you don't notice -- but any 
IMAP operations that are in progress at the time will of course fail.  
   
 Check your process table (ps ax | grep citserver) before and after such 
an operation.  You should see two instances of citserver; one is the 
actual server and the other is a monitor process.  If one of those pid's 
changes but the other stays the same, then you've got a crashing server.  
   
 Not to worry, though; we're really good at isolating these and pushing 
updates out quickly, so stay in touch and we'll get you back on your feet.
