[Mimedefang] problem with mcafee virus scan (uvscan) on RH Linux 9

[Gus.Buerkle at trilogy.com]

I know this isn't exactly the correct list for this problem, but I'm 
hoping that someone's seen a similar situation at some point.

I was attempting to configure uvscan to be executed from mimedefang (as 
suggested in Mickey Hill's mimedefang howto) but found that the command 
would hang and cause the milter to timeout- turns out that running uvscan 
from the command line also hangs.  'ps' indicates the process is sleeping. 
 I saw a similar post on this list suggesting that uvscan was somehow 
checking the cd and / or floppy drives for every run - maybe that is 
involved in this case?  From the below strace it seems that some sort of 
device checking is related to the problem.

Unfortunately I don't have phone support from NAI / McAfee, and I've 
submitted an email trouble ticket but haven't heard from them.  No source, 
and obviously no debugging symbols in the executable either...

i'm still investigating the strace: here are the last few lines.

write(1, "This program is more than   5 mo"..., 71) = 71
open("/usr/local/uvscan/messages.dat", O_RDONLY) = 4
lseek(4, 6799, SEEK_SET)                = 6799
read(4, "\37\216\277\16\354\360U\37\247.\346\"\32-4\\\307\320n\203"..., 
4096) = 4096
close(4)                                = 0
write(1, "time - we would suggest that you"..., 52) = 52
time(NULL)                              = 1054755930
open("/proc/devices", O_RDONLY)         = 4
fstat64(4, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) 
= 0x402f6000
read(4, "Character devices:\n  1 mem\n  2 p"..., 4096) = 371
futex(0x8085df0, FUTEX_WAIT, -39, NULL <unfinished ...>

...

RH Linux 9, kernel 2.4.20 (stock)
uvscan v4.2.40

thanks for any ideas
