. When this happens, the system log displays the following
message:
log records lost
The lost records are those that should have been recorded in the FW-1 log
message file (typically located in the $FWDIR/log directory).
You can use one or both of the following solutions to resolve this issue:
!
Reduce the number of rules that are logged by:
!
Disabling as many accounting rules as possible
! Changing as many long logging rules to short logging as possible
!
Eliminating logging entirely if it is practical to do so
!
Increase the size of the kernel module buffer
Note
To perform the following procedures, use the zap or modzap utility
(which you can obtain from the Nokia Technical Assistance Center
(TAC); refer to Resolution 1261).
If you are using FireWall-1 4.1, do the following:
1.
Set the execute permissions by issuing an
fwstop
command.
2.
To confirm that you have sufficient resources to increase the buffer
size, issue the following command:
# ./modzap -n _fw_logalloc $FWDIR/boot/modules/
fwmod.o 0x20000
where
0x20000
indicates a buffer size of 2MB, and the
-n
option
causes
modzap
to check the value at the symbol reported.
3.
A console message is displayed confirming the change that will take
place when you issue the modzap command in the next step. You can
safely ignore this message.
