Description of problem:

Kernel hang while running Cyclone (http://www.highwinds-
software.com/products/product.aspx?productID=4&pageID=1)
System unresponsive. Physical reset required.

If the system is configured to handle more than a few feeds and 
network traffic goes beyond 40mbit/s the system will crash within 10 
seconds of starting Cyclone. Fiddled with multiple hardware including:

Intel STL2 mobo with dual 1ghz-p3, mobo has intel 100 ethernet
Supermicro Superserver 6013P-8 with dual 2,8 Xeon's, w/ & wo/ HT, 
mobo has dual intel copper gige
Storage as 5x IBM 36gb 10k SCSI (IC35L036UCD210-0, rev S5BS) on an 
external u160 box or in internal slots of Intel SC5000 case.
Megaraid Elite 1600 running JBOD or RAID5
Adaptec 7902 w/ & wo/ 2005S ZCR running JBOD or RAID5
Two channel Symbios 896-based u2w-card running JBOD
Intel dual port 1000MT gige PCI-X

Version-Release number of selected component (if applicable):
2.4.21-9.0.1.ELsmp

How reproducible:
Every time

Steps to Reproduce:
1. Install RHEL3 U1, update to current
2. Get Cyclone, configure more than a few feeds
3. Start Cyclone
  
Actual results:

Additional info:

Currently running Arjan's 2.6.3-2.1.213smp on STL2 mobo with Symbios, 
disks in the external case. Connectivity with internal e100. Crashes 
every few days and spews errors continuously.
