Well, I'm on a Linux system so I'm not sure what to look for. Since this is my work laptop, it does have ipchains (or iptables maybe) rules setup but I think that's mainly for inbound traffic. I've never had any outbound traffic issues and as it's not a "personal" firewall product it doesn't prompt to allow traffic that gets caught by a rule. This laptop also has Symantec Antivirus (yeah yeah, on a Linux machine... take it up with the silly corporate people) but I've checked and that's not running too much. Those heartbeat issues seemed to coincide with a lot of disk I/O though. Does DDDT write a lot of stuff to disk like the old HDC project that used to write several hundred meg files to disk?

That is what is missing I kept scratching my head going why are the messages sooooo BORING now in 5.10.28. Thanks Sek!

Hello Lone-Wolf,
What system diagnostic program have you run to check out your system's hardware?

If it does, supplant your cc_config.xml with this content:

<cc_config>
  <log_flags>
    <task>1</task>
    <file_xfer>1</file_xfer> 
    <file_xfer_debug>1</file_xfer_debug>
    <proxy_debug>0</proxy_debug>
    <http_debug>0</http_debug>
    <checkpoint_debug>1</checkpoint_debug>
  </log_flags>
  <options>
    <save_stats_days>90</save_stats_days> 
    <dont_contact_ref_site>0</dont_contact_ref_site>
  </options>
</cc_config>

(some motivation may have come from crunchers who 'advised' that the transmission speeds were 'incorrect', so hid it by default)!

I get a similar problem intermittently on two different machines. One, a P4 2.4GHz machine with 1Gb RAM, the other a XP3000+ also with 1Gb RAM. Neither machine is overclocked, both are running Ubuntu 7.10 and neither show anything in any logs I've looked at. They just ... stop. Most units go through fine, it's just the odd one the stops for some reason.
