Server was working just fine for years and recently started to stall
completely after 3-7 days of functioning normally. error logs get filled up
first with AH03490 and then eventually with AH00045 messages:

Have you tried increasing ServerLimit as the warning suggests?
Apart from that, it is probably the same as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1057126 . mod_wsgi or
some python script is preventing apache processes from dying and they
accumulate until the scroeboard is full. Which versions of the wsgi
related packages are you using?
