Suppress/Fix Warning Message "Client sent SYN_STREAM for non-increasing stream ID"

[Vlad Lasky]

Hi,

A website I administer is running CentOS 6.4 with Apache 2.2.15-29 and mod-spdy-beta 0.9.4.1-397.

Apache SSL's error log file is full of lines like this:

[Mon Mar 10 23:42:09 2014] [warn] [client xx.xx.xx.xx] [mod_spdy/0.9.4.1-397] [32267:32267:WARNING:spdy_session.cc(389)] Client sent SYN_STREAM for non-increasing stream ID (30231 after 32767).

These lines are continually added almost every single second. The number at the end of the line is always 32767.

I am not sure why this warning is generated. Perhaps it's because some visitors are running older versions of Chrome?

Whatever the reason, is there a way to fix this. Otherwise, can you please release a new build of mod-spdy with the option to suppress these warning lines being added to the SSL error log. They don't give me any useful information, they make the SSL error log file enormous and they make it harder to sift through the file to locate other errors unrelated to mod-spdy.

Thanks.
