Roberto Resoli commented on DAEMON-192:
---------------------------------------

I agree. In the meantime, I found that setting limits it's only matter to run 
ulimit ( in order to set max number of open files, for example: "ulimit -n <max 
number of open files>" ) just before of launching jsvc. 
The limits are retained even when jsvc running user is downgraded.

> Make jsvc enforce /etc/security/limits.conf , or add a parameter for setting 
> limits

> When launched with -user parameter, jsvc downgrades user via setuid() system 
> call, but the operating system limits (max number of open files, for example) 
> remains the same. 
> This is not convenient for running daemons (like Tomcat) which very often 
> need a customization of such limits.
