Hi,
It seems when using rfcomm_pppd (at least) as a Bluetooth <-> LAN
gateway there is a fairly large memory leak which eventually crashes
the box running the ppp server. To track down where, I recorded the
output of kern.malloc every minute until the box crashed. At the
start of the debugging run, I saw:
devbuf 441 2650K 2861K 2504
16,32,64,128,256,512,1024,2048,4096,8192,16384,65536
A mere 32 minutes later (right before it crashed), it was up a
considerable ammount:
devbuf 89943184451K 184451K 92399
16,32,64,128,256,512,1024,2048,4096,8192,16384,65536
I'm pretty sure that kernel virtual memory got exhausted and the
machine paniced and rebooted.
I'm not even sure where to start looking for this. I'm using a MSI USB
dongle:
ubt0: vendor 0x0db0 product 0x1967, rev 1.10/5.25, addr 2
ubt0: Interface 0 endpoints: interrupt=0x81, bulk-in=0x82, bulk-out=0x2
ubt0: Interface 1 (alt.config 5) endpoints: isoc-in=0x83, isoc-out=0x3;
wMaxPacketSize=49; nframes=6, buffer size=294
% sh /etc/rc.bluetooth start ubt0
BD_ADDR: 00:10:dc:e9:59:f4

<Paging scheme> <Power control> <Transparent SCO data>
Max. ACL packet size: 192 bytes
Number of ACL packets: 8
Max. SCO packet size: 64 bytes

This is on -current from approx. Aug 14 2003.
The other end (client) was another MSI USB dognle on a Windows laptop.
Any ideas?
Thanks,
Gary
