on my not so busy i386 4.0-current web server I get "uvm_mapent_alloc: out of
static map entries" ~ once every two days. The archives bear a wide range of
suggestions, from tweaking kernel feature xy to not touching anything, because
that's stupid.
However, this message bothers me a bit and so I am seeking for advice how to
track the problem down (if any).
The machine runs apache with mod_gzip, openssl and php5 plus myqsql. I have set
those up in a most default way, for mysql I've followed the guidelines on
openbsdsupport.org.
below you'll find output of vmstat -m, netstat -n and ps aux
thanks,
Stephan
