Webalizer stats stopped to be updated for a few domains.

We have a few domains (accounts) on our server. Some of them are fine with Webalizer stats and graphs. But noticed recently that some domains are not updated from Oct 2014 when we want to see their Webalizer stats in Direct Admin.



We've found that /var/log/directadmin/errortaskq.log has the following info:



2015:01:26-00:25:57: Unable to run webalizer for pNNNNNNNy.com: Webalizer V2.01-10 (Linux 2.6.9-89.0.29.ELhugemem) English

Using logfile /var/log/httpd/domains/pNNNNNNNy.com.log.1 (clf)

DNS Lookup (10): Error: Unable to restore run data (99)

325 addresses in 25.24 seconds, 12/sec

Using DNS cache file /var/cache/pNNNNNNNy.com.dns_cache.db

Creating output in /home/user56/domains/pNNNNNNNy.com/stats

Hostname for reports is 'pNNNNNNNy.com'

Reading history file... webalizer.hist

Reading previous run data.. webalizer.current



We have about 10 domains and not all are with errors, just a few, so we cannot find the reason why that happened for some accounts and why all is fine for other accounts.



Can someone suggest the way to return webalizer to work for all our domains?

Thanks
