Hello

I have 3 processes to be executed in a particular sequence.
ProcessA
ProcessB
ProcessC

The requirement is that all the processes should run as background processes.
ProcessA talks to ProcessB and ProcessC using sockets.
ProcessB talsk to ProcessA only using sockets.
ProcessC talsk to ProcessA only using sockets.

Two situations:

* If ProcessA is started in background, ProcessB in foreground and ProcessC in background, all is well and good.
* If ProcessA is started in background, ProcessB in background, then the moment ProcessC in started (either foreground or background), shell hangs, telnet/ssh to the target fails.

Environment:

OS: MontaVistaLinux
Processor: PowerPC
Shell: sh
Language: C
ProcessC: NetSnmp Agent (snmpd)

More details:
The processes are started through a shell script "start_me.sh" - ProcessA is started first
- Sleep for 3 seconds
- Start ProcessB
- Sleep for 30 seconds
- Start ProcessC

Pipes are used by ProcessB only for its internal task communication purposes only.
Inter Process Communication is through loopback TCP sockets.

What can be going wrong here?

Greetingz!

Maybe I'm missing something, but "Shell: OpenBSD" doesn't make any sense to me.
Wouldn't that be "csh, ksh, bash, sh, zsh" or the like?

Regardless, are you starting ProcessA, ProcessB, and ProcessC all in the same terminal window?
What happens if you open 3 terminals (xterms, Konsoles, etc), and then start & background each process?

Sorry, Shell is sh. Edited the post.

The behaviour is the same.

Is there any way you could post the code?
