webpagetest agent restarts
Hi,

I have a problem. One of my agent machines restarts everyday after many hours of operating properly. I tried to figure out why it happens but with no results. Can anybody help me please?

The agent configuration:

[Configuration]
Startup Delay=0

debug=1

Log File=c:\webpagetest\log\log
Timeout=60
use current account=1

; Where to get work from
Url Files Url=http://[myinternaldomain].com:88/work/
Location=KRK1
Location Key=ABBAQQ122334

Reboot Interval=0

What I see in the log is:

Hi

it's not clearly said in the documentation, but the agents are configured to automatically reboot, to free up memory : https://sites.google.com/a/webpagetest.o...-instances

RE: webpagetest agent restarts
But it happens only to one of my agent machines and I really struggle to figure out what is the difference. Same version of the agent, same operating system etc.

RE: webpagetest agent restarts
I believe urlblast will automatically reboot if it gets 3 serious failures in a row (dns lookup, etc) on the assumption that something is wrong with the network or machine. My bet is that whatever caused the "enough storage is available to process this command" error in the log was enough to trigger the reboot.

Is space available on all of the drives? Theoretically it should stop getting work if there is < 100MB available anyway but something strange is going on with launching the browser.

Thanks Patrick!

I'll try to figure out what causes this message in the log.

For sure there is enough storage available.

RE: webpagetest agent restarts
Finally I figured out that the problem is because of "Out of memory" windows error message.
