Are you sure that 2048 is enough? You didn't really provide these
details, but assuming you are using the FileLog and FileStore, that's 7
descriptors per session just for those files alone, or 1,953. Doesn't
leave you enough for the sockets for sure. When you say it works at
103, is that to say that 104 doesn't work? What do you get from 'ls -l
/proc/<pid of quickfix app>/fd | wc -l'?
If you are using a FileStore, it's pretty useless to do so since you
have ResetOnDisconnect and ResetOnLogout set to Y. You might want to
switch to a memory store (will increase memory usage). Or if this is
some sort of high speed market data line (looks like it might be based
on this configuration), a NullStore may be an option.
