files open limit

[Peter Choe <ch...@mindspring.com>]

i have been getting an error on my FreeBSD 3.4 system which is running 
tomcat 3.2.  after a while, i get a 'too many files open in system' error 
and it freezes tomcat and the whole server.

i looked at the ulimit on the system and it says that the file limit is 
1024.  i have no idea if this is too low normally.  it seems to be too low 
for my usage.  i even went back to check my webapps to make sure that i am 
close all the connections, but it seems that some connections, files and 
databases, are being kept open.  is there anyway to know which webapps are 
causing the problem?

  Try using lsof, this tool could help you telling which fd are opened 
by a specific process:
    # lsof -i -n|grep PID
