Server non-responsive - no related errors or crashlogs

[Gorian]

The Environment:

• The Physical Host:
  • CPU:
    • 2 x Intel Xeon E5620 2.4Ghz
  • Chassis:
    • 1 x SuperMicro SC811 1U
  • Hard Drives:
    • 1 x Western Digital 1TB RE4 FBYX SATA
  • Motherboard:
    • 1 x SuperMicro X8DTL-iF
  • RAM:
    • 5 x Actica 4GB DDR3 1333 ECC Registered
• The Virtual Server (Tekkit Host):
  • OS:
    • Ubuntu 12.04 64bit
  • CPU:
    • 4 Cores
  • RAM:
    • 8GBs
  • Hard Drive:
    • 45GBs
  • Game Server:
    • >Tekkit 1.2.8e(recommended) (with MCPC+)
  • Other:
    • McMyAdmin (licensed,stable)

The Issue:

The server hangs at startup with NO (seemingly relevant) errors, or crash logs.

Logs:

• Server.log
• ForgeModLoader-server-0.log

Solutions Tried:

• running without MCPC+ (no plugins)
• running without McMyAdmin
• removing DIM_MYS134 (last entry in log)
  • unless I remove world/data/agedata_134.dat it recreates the world. Removing that file results in trying to load a non-existant world and severe errors (not sure how to tell it not to)
• changing ChickenChunk Chunk Loader to id 0

EDIT:

 

After a LOT of troubleshooting,seems the problem was with ChickenChunks or something it was loading. Disabled the mod and the server starts.

Have you tried making a backup and removing a mod one at a time? It may be tedious, but it'd help you find the issue if the cause is infact a mod with no logs. You could also try profiling the server while it hangs, using tool such as VisualVM, WarmRoast or Opis (not sure of Opis will provide the information you need, but it may).

yeah, eventually did that and found it was ChickenChunks (notice my edit)

 

Couldn't use anything like opis, since the server wouldn't respond to any commands.
