SPDY inflate errors in nginx 1.7.4

[tunist]

i am seeing many error log messages relating to SPDY on an HTTPS only
website here. this appears to also be triggering (or at least related to)
database timing problems, which is causing dbase failures.

the error log contains mostly these:

"inflate() failed: -5 while processing SPDY"

anyone know what's occuring here? i think i already asked a similar question
on a forum and someone pointed to the possibility of there being attempted
exploits made against SSL3 / openSSL - though i have no direct evidence of
that.

thanks
