Looks to me suspiciously like an issue with wget instead of tomcat. 
Wget is making an attempt using a stale cached connection, failing, and
retrying.  For some reason the result of the retry isn't present in the
stdout file.

You could try adding the -S option to wget and then check for the string
'HTTP/1.1 200' instead.  That seems to me to be a more reliable method.
