pfSense has menu options that allow to move/create /tmp and /var in RAM. These can be found in System>Advanced>Miscellaneous.
Then logging would be written to the RAM disk. Note that the logs will be lost when the power goes out. You will need to setup a scheduled job that does backups if you wish to persist the logs across reboots. Also note that all file systems slow down as the get full. As flash runs out of empty write blocks, its performance also suffers. Something you might try is the replace the existing flash card with something 2x-4x times larger. You might try getting the lsof package/tool from a FreeBSD 8.3 machine (assuming you are running the current version of pfSense) and installing/copying it to your system. FreeBSD has two commands that provide many of the features in lsof: fstat sockstat pfSense has both of these commands installed.
