Hi Paul,
thanks for getting back to me on this.
I don't think it is firewall issues because up till now the backup
ran fine. Actually it ran fine last night. Nobody was doing any big
calculations on it, which could have affected that. Also, so maybe
something else strange on the network was going on.
Is there a way to affect the 30 sec timeout for the planner's ACK
timeout?
Cheers,
René

Hi,
I have been running into problems that some of my systems are
heavily used for long computations making them somewhat less
responsive.
Last night I ran into the issue that four systems did not send
acknowledgments back to the dumper on time during the planning
process:
planner: ERROR Request to werner.richmond.edu failed: timeout
waiting for ACK
I looked into allowing more time for that stage, which I believe
etimeout should allow, but my amanda.conf has 'etimeout 600' in it
while the planner's debug file ends with:
security_seterror(handle=0x3038a0, driver=0xa2a0c (BSD)
error=timeout waiting for ACK)
security_close(handle=0x3038a0, driver=0xa2a0c (BSD))
planner: time 29.898: pid 3734 finish time Tue Nov 27 00:45:36 2007
suggesting that it still only waits for 30 seconds.
planner sends a packet to the client(s) and it expects at least
an UDP ACK-packet back within 30 seconds, indicating that the
client did receive at least the request.
The etimeout is the time that planner will wait for the packet
with the different size estimates from the client, which will usually
take more than 30 seconds.
Am I setting the wrong timeout?
So it seems you can't even get a reply back. Firewall issues?
