I had the same problem. From what I've seen, the acct.c is the problem. It
uses lseek when it deletes users from radutmp file. Here's a snip of the
code:

if (lseek(fd, -sizeof(u), SEEK_CUR) < 0) {
	log(L_ERR, "Accounting: negative lseek!\n");
	lseek(fd, 0, SEEK_SET);
	}

On FreeBSD -sizeof(u) generates 32-bit result, but FreeBSD lseek expects
64-bit offset. Thats why your file grows to (4096MB - 100 bytes). I
changed all -sizeof(u) arguments to -100, and everything seems to be
running fine now for 3 weeks.

Yes, I have one, which uses pmwho command. It has two problems:

1. The multilink ISDN connections are not detected properly, since USR
shows < MPlink: I* > as a username which is hard to match properly.

2. Multiple pmwhos take so long to execute, that radiusd starts to
timeout. I fixed that by bumping up timeout in radiusd.h:

< #define MAX_REQUEST_TIME        30
> #define MAX_REQUEST_TIME        120
