Strange crash happening constantly on high-traffic webserver

[JM]

Hello all,

 

    I'm hoping someone can help me out here because I'm at a loss.  I've got
a Dual Xeon with 4 gigs of mem running apache 1.3, mysql is on the server
but not really heavy usage.  The following keeps happening at random times,
but guaranteed every day:

 

panic: kmem_malloc(4096): kmem_map too small: 335544320 total allocated

cpuid = 2

Uptime: 13h48m2s

Dumping 4095 MB (3 chunks)

chunk 0: 1MB (159 pages) ... ok

chunk 1: 3327MB (851648 pages)

 

Has anyone had this issue before?  I'm running FreeBSD 6.2-RELEASE-p2 with
PAE and SMP support compiled into the kernel.

 

    Thank you VERY much for your input!

 

JM
