file descriptors

[Jon Rowell]

I am currently getting this error from master:

Apr 28 12:02:37 weathersby master[31748]: setrlimit: Unable to set file 
descript
ors limit to -1: Operation not permitted
Apr 28 12:02:37 weathersby master[31748]: retrying with 1024 (current 
max)

And then later I get an error about too many open files.  How can I up 
the number of allowed open files?  I am running linux and cyrus 2.1.12.
