Odd Error on Dojo II causing server "no-start"

[CmdrNoval]

This is written with Karl or Eric in mind, but anyone with server knowledge is welcome to respond.

Ran into an unusual error on a server that has been running for years...

Important points:

-No changes have been made to the server configuration files in many months.

-Server is running on year old hardware, and an SSD, (thru JestServers) which pretty much eliminates file fragmentation as a possible cause.

-Updates to Altitude and/or Java itself have not been eliminated as a cause.

-My other server, running on the same hardware is completely unaffected.

Here is a server launch log snippet for analysis:

Jest (@JestServers) is working on the issue, but is not completely versed on Altitude Servers as this community is...

Any help or ideas would be greatly appreciated...

Well.., nevermind all...

After analyzing the stack, it appears that Java was calling up a file from the cache that had been overwritten... (was basically a header and half of line one)

Cleared the cache & re-launched.

Dojo II is back in business.
