[FW1] "bad file number" after installing sp4

Title: "bad file number" after installing sp4

After applying SP4 (I redid it after failing because of too large directory name - if that have anything to do with it) fw1 (v4.1 on solaris sparc 2.7) fails to install the security policy. The message is:

....
...
Compiled OK

....
Downloading on localhost succeded.

Installing security policy on
Has only loopback (lo) interface, aborting.
Failed to load security policy. Bad file number.
Installing security policy on localhost failed.

* I tried uninstalling the service pack, but no change.
* When doing "fw ctl iflist" it only lists the loopback interface.
* The license seems to be ok.
* I tried the things in one FAQ I found on www.phoneboy.com: "fw ctl uninstall/install", dumb terminal file, verifiying /etc/init.d/firewall1 exists and verified /etc/fw.boot/ifdev. Well.. everything except "cpconfig -install".

What to do except reinstalling (if I lose the policy it doesn't matter, I can always redo it)
Any help would be appreciated.
