SPDY inflate errors in nginx 1.7.4 - 1.7.7

[tunist]

enabling debug on the site in question generated vast amounts of log data
and i think either some type of limit was reached or a bug caused the
logging to fail. i was unable to open the logviewer for the site's error log
after the first few minutes and eventually the interface crashed while
attempting to open the log.
now i have disabled debug again and can open the log. the logging stopped
shortly after i initialised the debug directive for nginx, so there is no
useful debug info pertaining to the SPDY issues yet.
i'm not entirely sure what to do here..
has anyone seen this type of behavior before?
thanks
