Mladen Turk commented on DAEMON-270:
------------------------------------

I'm not sure why would that be a bad thing and why would that be a major issue.
>From your comment it is clear that if you set user's 'ulimit -u unlimited' it'll work.
Anyhow, it can just be a bug in the linux kernel.

> For jsvc, start fork process to start JVM, then downgrade the process capability to 0.
> Is it really requirement? or any concern? 
> For my test env, it happen can't start more threads in the java.
> After the check, it is limited by "ulimit -u" max process for user. It is very interesting things, actually it doesn't control threads by this attribute in the normal process.
> Downgrade the process capability cause this issue. Max threads number should be control by env memory, kernel max threads parameter, stack size.
> For my suggestion, could remove downgrade the process capability, only inherit the parent's process capability and add some "read/netbind/setuid.." extra privilege if don't have.
