I've ran across the following errors at random in my rails app:

Code:

A Timeout::Error occurred in users#create:

 execution expired
 /usr/lib/ruby/1.8/timeout.rb:54:in `rbuf_fill'

-------------------------------
Backtrace:
-------------------------------

 /usr/lib/ruby/1.8/timeout.rb:54:in `rbuf_fill'
 /usr/lib/ruby/1.8/timeout.rb:56:in `timeout'
 /usr/lib/ruby/1.8/timeout.rb:76:in `timeout'

If I look in the LS error logs I see this:

Code:

Notice the "left in buffer: 0". I am sure no one restarted/stopped the server either.

What does this mean? If I do "free -m" there is plenty of memory on the server (a 512MB VPS), should I up the Rails app buffer/timeout settings in LS? Or does this have nothing to do with LS? Thanks for any info.

Code:

Server Restart Request via Signal...

Someone tell LSWS to restart by sending signal to the server process.
How often does it happen? Is there any cron job restart LSWS regularly?
