Subject Re: Zookeeper stops
Date Thu, 19 Aug 2010 14:34:49 GMT
Hi Wim,
  It mostly looks like that zookeeper is not able to create files on the /tmp filesystem.
Is there is a space shortage or is it possible the file is being deleted as its being written
to?

Sometimes admins have a crontab on /tmp that cleans up the /tmp filesystem.

Thanks
mahadev

Hi,

I have a zookeeper server running that can sometimes run for days and then
quits:

Is there somebody with a clue to the problem?

I am running 64 bit Ubuntu with

java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)

Zookeeper 3.3.0

The log below has some context before it shows the fatal error. Our
component.id=40676 indicates that it is the 40676th time that I ask ZK to
publish this information. It has been seen to go up to half a million before
stopping.

Regards,

Wim
