Hi all,
I'm getting to many errors on my ftp server. The scenario is:
- I have ftp server embedded on my app
- I have about 50 connections:
- Its about 15 ~ 30 computers
- Its about 2 ~ 3 connections per IP
- Config (server):
- maxlogins= 400
- maxthreads = 20
- Config (user):
- idletime = 1200
- maxloginnumber = 0
- maxloginperip = 0
- The error occurs to any of computers. I mean, it doesnt occur for an
specific IP
- The network is stable (FO)
I dont know if I can post log here because the email size ... I dont, please
let me know.
This is the log:
