Re: Kernel Parameter
What changes did you make? also cat /stand/system and post the * Tunable parameters section, in will help to identify the problem.

Re: Kernel Parameter
Maybe your problem is related to the kernel parameter "unlockable_mem".
Here is what I found on sam's help:
Specify minimum amount of memory that is to remain reserved for system overhead and virtual memory management use.
Acceptable Values:
Minimum: 0
Maximum: Available memory indicated at power-up
Default: 0 (system sets to appropriate value)

Re: Kernel Parameter
There is no:
dbc_max_pct
dbc_min_pct
shmseg
bufpages
maxvgs
listed.
Also, if you set bufpages you are overriding the fact that you want to use dynamic buffercache.
What is the physical memory size of your system?
What does dmesg show for Physical, lockable and available memory when you boot the system with the new kernel?
What were the reasons for increasing the parameters you increased?

Re: Kernel Parameter
The reason why I have increased some parameters was because I have doubled the physical memory from 256 to 512. Below is the information that you requested:
Memory Information:
physical page size = 4096 bytes, logical page size = 4096 bytes
Physical: 524288 Kbytes, lockable: 412292 Kbytes, available: 440816 Kbytes
Thanks,
Augusto

Re: Kernel Parameter
You should decrease your shmmax parameter (it's greater than your memmory size and it shouldn't), and maybe dbc_max_pct (to 10/15)
