Hi,
I saw Apache kept restarting a lot all of the sudden, and wondered why, so I checked the error log and saw this:

Its a Synology box, and I don't know how to update it manually to 0.9.4.3, but any idea what else I can check why this is happening all of the sudden? I didn't change/update anything for weeks and I can turn mod_spdy off, but i'd rather fix it.
Any help would be appreciated :)
