Ram

How do I increase the RAM allowed for a normal user?

Re: Ram

How did you limit it? Normally you can just go the other way.

That is to so say, please provide more info. Thanks.

Re: Ram

When I try to lock memory into the RAM as a normal user I get out of memory errors; however, when I try it as a root user it proceedes fine. (I have 3 GB DDR3 RAM available, and I am trying to reserve about 300 mb of it).

Re: Ram

I can only guess myself, what do you get as the output of the following,
cat /etc/security/limits.conf
free -m
ulimit -a

#Where:
#<domain> can be:
#        - an user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)

#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#

Re: Ram

I wonder if the last line in limits.conf has anything to do with it.

Re: Ram

But shouldn't that also apply to root?

Re: Ram

I don't think it should. Is root part of the audio group?

Re: Ram

No problem at all. I hope that fixes it. (And don't forget to mark the thread as solved if it does.)
