Hi all, last days I leased a virtual host at 1und1 (a german hoster). Unfortunately 1und1 found a new, creative way to limit the joy of using their VPH - they limit the number of operating-system processes to 256 processes in total.
Thats quite a huge issue, because I want to operate two virtual hosts:
apache-dev -- tomcat-dev -- mysql
apache-www -- tomcat-prod -- mysql
* mysql uses 50 threads in total
* apache uses 5
* tomcat_prod - 109
* tomcat_dev - 73
As u see, there is not much space left for chron jobs / ssh-shells a.s.o.
I tried to limit
* apache Maxclients (50 in total)
* mod_jk connection_pool_size (3/40), socket_keepalive=false
* server.xml:
<Executor name="tomcatDevThreadPool" namePrefix="catalina-exec-"
daemon="false" maxThreads="(3/40)" maxSpareThreads="5"
minSpareThreads="1"/>
<Connector executor="tomcatDevThreadPool" port="8009"
protocol="AJP/1.3" URIEncoding="UTF-8"/>
But all of these actions result in no change - and pstree shows the same
number of processes without any change (I use ubunut 10.4, java 1.6.0_20,
tomcat 7.0.11).
Any idea how to cope with this silly process limit?
Kind regards,
Michael
