able to reproduce this. I don't spawn (potentially) long running
jobs in this way. And anyway, my main production and test nodes

What you could try is to add a '&' character before the ") of
each spawn command. That will start a new process in background
and the spawn should return straight away.<span class="HOEnZb"><font color="#888888"><br>

Hi Mike,<br>
By any chance do you have any entries in your Spider
crontab with<br>
'spawn'?<br>

Attached image shows the DX Spider console… and
the server’s<br>
telnet console. I sure wish I could figure out
why Spider freezes<br>

and/or restarts randomly.____<br>
