I noticed that we have two heartbeats. From the IIS log:

...

Is this normal?

If there is more info needed, I'll be happy to provide it.

Yes, it is bad. While heartbeat sets a lock and does detect whether it is locked or not, multiple heartbeats running can cause big problems.

Shut down one service and send a mail. If the mail goes out, shut down the other service. Send another mail. If that one doesn't go out, restart one of the services and leave it like that.

We have only one FogBugz Maintenance Service and only one FogBugzMaint.exe *32 process. How can this cause two heartbeats...?! – Michel de Ruiter♦ Jan 18 2011 at 20:19

I restarted the (single) service and ProcMon confirmed thread 0 doing two TCP Sends and two TCP Receives every 15 seconds. Any ideas? – Michel de Ruiter♦ Jan 18 2011 at 21:11

Aha! Yes, it's probably multiple sURL keys in your registry. FogBugz will find all maintenance URLs and hit each of them. It's probably getting one from the 64-bit and one from the 32-bit registry. Can you check? Claudius is right in that there is protection against this messing things up too much. – Rich Armstrong♦ Jan 19 2011 at 16:46

Good thinking. However... I renamed the HKLM\SOFTWARE\Fog Creek Software\FogBugz\C:/Program Files (x86)/FogBugz/website key (because the Wow6432Node version should be used) and restarted the service, but I still see two heartbeats per 15 seconds in the IIS log. :-( – Michel de Ruiter♦ Jan 20 2011 at 22:56

ProcMon revealed that the renamed key was still used, even though it's an invalid path :-) . I removed it and all is well now. – Michel de Ruiter♦ Jan 24 2011 at 10:18

Is it okay to have two heartbeats?
