IP Address Not Configured Everyday at 1:15pm

[Adam]

I've looked and looked for anything similar to my issue, but was unable to find anything even close..

So, I have a Linux (CentOS 6.5) VM at Linode.com and it has Plesk 12.5.30 Update #21 installed on it.. For networking, I have 1 shared IP address (used for my primary domain, and all other sites) and then I have another site with an SSL which has a dedicated IP address.. In Tools and Settings -> IP Address, I also have a 10.0.0.1 IP Address (which is on the tap0 interface) and this is the required internal networking IP for Linode..

Now, I have two IP's that are bold.. the 10.0.0.1 IP address, and the dedicated IP address for the single site.. My primary/shared IP is not marked as a main IP..

Everyday at 1:15 PM all of the sites on the primary/shared IP go down.. I have to login to Plesk via the single site dedicated IP, go to Tools and Settings -> IP Address, click Reread IP.. When I do this.. my Primary/Shared IP refreshes with the error "This IP Address is not configured Properly", and has a link to Repair.. Once I click repair, it refreshes and the error goes away, and all of the sites come back on.. Until the next day at 1:15pm..

*I can't really do this http://kb.odin.com/en/943, as the sites are already live on all IPs
*I have also checked the default IP address within the psa database, and it is the correct Primary/Shared IP address.. But, the IP address in the system overview is the single/dedicated ip address which was added almost a year after I set the server up..
*This seemed to just start happening about a week ago.. I have had both IPs on there for almost a year..

Any help on this would be greatly appreciated as it is getting old to fix the server every day at 1:15..

I suppose that you have checked already all crontasks on Plesk server which may be run at 1:15pm? Or it is related periodic task from Linode side?

Yeah, I don't see anything that runs at 1:15 other than watchdog stats.. and its 01:15 so im guessing that 1:15AM..

I don't have anything set to run at 1:15 via Linode.. but I can send them an email and ask..

Update #1: Linode doesn't have anything running that would affect this.
Update #2: I restarted my server again yesterday to make sure that it wasn't some random glitch. It seems that my IP address get's messed up every 24 hours, not at 1:15PM.. So after the server has been running for 24 hours exactly is when the problem occurs..
