Repeatedly having to "restart task router" to deliver email

HCL Domino Domino Forum
1

I have seen this problem mentioned in this forum several times over the last several months but never with an adequate solution.

I have email that will not deliver because it fails with a “transient error.” It happens intermittently but once it starts various other messages begin to hang as well. Not all of them, just random domains become undeliverable to.

If I issue a “restart task router” at the console, either all of the hung messages get delivered or some do and some don’t. Sometimes an additional “restart task router” will get the rest of them, sometimes not.

My question, since an acceptable solution has not been presented, is is this being fixed in the 8.0.2 release scheduled for August or does someone have a better solution than “restart task router?”

Thanks,

Ned Grubb

Subject: I had this exact issue today

Mail was not routing to one domain. I restarted the router and it went straight out.

We had this problem a while back. In the end I found some information which gave hints as to the problem. I can’t find the exact links now.

The problem for us related to the internal windows DNS servers. The eventual fix was to point domino to external DNS servers. This was achieved by putting an entry into the notes.ini

dnsserver=x.x.x.x,x.x.x.x

I switched to a different outbound datacenter which may or may not use different dns servers (I haven’t been able to confirm yet).

The other datacenter worked fine.

Subject: Thanks, but not the solution…

Thanks for the suggestion but it had no effect on my problem. I added the dnsserver line and values to the notes.ini and restarted the system last night but the problem persists today.

Thanks again.

Subject: Problem defined: AT&T DNS server outage

The problem turned out to be DNS trouble with my ISP (AT&T). I swapped the order of the DNS servers in the TCP/IP configuration on the Domino/Windows 2003 Server and email immediately began flowing properly.

Thanks for the mention of DNS as the likely culprit as it led me to the solution.
