Too many users on Linux?
 

Hi All,
We've got a problem with one of our servers. Shes a big baby running RH Linux 7.0 and has been serving her 50 or so users very well. Yesterday we imported a Progress DB and app, giving her a further 30 users to accomodate. Now, it seems, that out of the 80 users/clients (TCP/IP connections needed) she can only serve 63 at one time. Is there a default number of maximum TCP/IP connections that a RHL machine can handle? and if so can one (and where) modify it??.

Thanks to all, and to this Website.

For me it looks it's rather the program's problem, not Linux itself. I don't know the app you're using so I can't help more.

postgresql by default is setup to max out at 32 users. if that helps

I'm not sure but it could be software related like turnip and mara stated but to open more ports for tcp/udp to be used simultanously, you can issue a command like this:

echo 1024 25000 > /proc/sys/net/ipv4/ip_local_port_range
