Hello, imho maxsparethreads is too low as well as maxrequestsperchild, which will make your server reclaim threads too often, this often causes the scoreboard full warning (although it is not an error, just a little degradation from my experience testing).
Can you try to adjust maxsparethreads to something above the average load you usually have? Say you have a typical use of 1000 threads, rise it to 1500 or 2000, or even 5000. Also if you can set maxrequestsperchild to a very high number (10 million) or to 0, unless you suspect a mem leak. 2017-03-16 12:14 GMT+01:00 Stefan Priebe - Profihost AG < s.pri...@profihost.ag>: > Hi Yann, > > no sure whether this is due to your mpm event patch. > > From time to time i see the following error mesages in my logs and the > only chance to fix it is to restart apache. > > [Thu Mar 16 01:00:35.445184 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > [Thu Mar 16 01:00:36.446178 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > [Thu Mar 16 01:00:37.447181 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > [Thu Mar 16 01:00:38.448177 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > [Thu Mar 16 01:00:39.449185 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > [Thu Mar 16 01:00:40.450184 2017] [mpm_event:error] [pid 27485:tid > 140212799559552] AH: scoreboard is full, not at MaxRequestWorkers.Increase > ServerLimit. > > Settings: > ServerLimit 50 > ThreadLimit 200 > ThreadsPerChild 200 > MinSpareThreads 200 > MaxSpareThreads 400 > MaxClients 10000 > MaxRequestsPerChild 10000 > > MaxRequestWorkers isn't set at all. > > Greets, > Stefan > -- *Daniel Ferradal* IT Specialist email dferradal at gmail.com linkedin es.linkedin.com/in/danielferradal
