[Asterisk-Users] Too many open files

[Raymond Chen]

Dear all,

we have encounter problem when starting asterisk in the foreground,   
"asterisk -vvvvgc"  with more 100 SIP calls concurrently.  we have set 
ulimit to the highest value. still has this problem.  Is this the 
problem keeping asterisk in the foreground or this is a bug in SVN 1.2 
16771?
