A strange report recently came in for which I've found no precedence in ColdFusion's history. A system adminstrator installed Update 4 for Red Hat Enterprise Linux 3 (v3.4) with the 2.4.21-27 kernel, and 2.4.21-27.0.2.ELsmp and now after 1 or 2 days of uptime the system encounters a kernel panic and stops, where the ColdFusion MX 6.1 U1 cfusion process is highlighted at the console:

Process cfusion (pid: 7392, stackpage=df8df000)
Stack {...bunch of hex values here}
Call Trace: [] __free_pte [kernel] 0x242
....
Code: 0f 0b e1 00 a7 ....
Kernel panic: Fatal exception


I've not found any past case of kernel panic for ColdFusion anywhere, and even Google turns up empty, so this looks like a first to me.

If the sysadmin rolls boots an older kernel then the system is stable. The sysadmin reports that Red Hat recommends the new kernel to them.

That's all I've got right now, but just thought I'd share in case a CFMX/Linux user runs into this.
