Subject [jira] Commented: (DAEMON-192) Make jsvc enforce /etc/security/limits.conf , or add a parameter for setting limits
Date Tue, 18 Jan 2011 07:38:43 GMT


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.

>            Priority: Minor
> 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.
