I have installed and run the cygwin inetd telnet server and find that
when more than around 16 users connect via telnet the shells start to
fail with the following message:
16622413 [main] -bash 3868 fork: child -1 - died waiting for longjmp
before initialization, retry 0, exit code 0x80, errno 11
-bash: fork: Resource temporarily unavailable
Are these connections starting simultaneously?
No, these are user telnet sessions.
Each session starts a sh.exe, an in.telnetd.exe and one or more
application processes (though so far weâve only loaded 2). Each or these
processes takes between 4Mb and 10Mb memory according to Windows task
Manager.
We need to be able to run at least 24 telnet connections using an
average of 3 application processes.
The machine weâre using is a Xeon processor with 4Gb Ram running Windows
2000.
Normal Xeon or one of the new 2-core Xeons?
2 core - 4 processors
Can anyone help?
Not at this time, if the answer to my first question is yes then perhaps
you are
running into a Windows limitation which AFAIK exists only in XP-SP2; if the
answer to the second question is yes there has been another thread that
reports
problems with 2-core processors and possible workarounds.
I checked the workarounds and these refer to random fork errors which looked
promising, although the errors aren't really random. Using Process Explorer
to limit the CPU's used, as suggested, didn't do the trick.
Does anyone have a 'plan B'?
Thanks
Nick
