[Xorp-users] xorpsh hanging on 'show pim join'.

[Ian Batterbee]

Hi, I'm seeing some unexpected behaviour through xorpsh, in that the 
backend module appears to become unresponsive.

If I issue "show pim join" repeatedly, the first few requests succeed, 
then subsequent commands never return - after about 15 (guess) seconds, 
the xorp_rtrmgr process says:

"[ 2007/07/24 17:52:10  ERROR xorp_rtrmgr:20556 FINDER +85 
finder_xrl_queue.hh dispatch_cb ] Sent xrl got response 211 Reply timed out"

but xorpsh continues to wait until I hit ^C, at which point the rtrmgr says:

[ 2007/07/24 17:52:56  ERROR xorp_pimsm4:20566 LIBXORP +213 
buffered_asyncio.cc io_event ] read error 104
[ 2007/07/24 17:52:56  ERROR xorp_pimsm4:20566 XRL +159 xrl_pf_stcp.cc 
read_event ] Read failed (error = 104)
[ 2007/07/24 17:52:56  ERROR xorp_pimsm4:20566 XRL +338 xrl_pf_stcp.cc 
die ] STCPRequestHandler died: read error

...presumably in response to me aborting the request.

At that point, I can *occasionally* press [up] in xorpsh and the command 
works, but most of the time it hangs.

if I shut xorp_rtrmgr down, and then restart it, things are okay again 
for a few minutes, and then the problem begins once more.

xorp is speaking PIMv4 to a cisco router which connects to a 
education/research network, which has a lot of multicast traffic on it. 
Could the amount of sources could potentially be the problem ?

If I simply start xorp_rtrmgr up, and then wait 5 minutes, the first 
time I issue 'show pim join', the output hangs.

It *may* also have something to do with me piping the output through "| 
no-page " or "| find 233.0.76.26".. I'm not sure if that's related but I 
thought I better mention it in case it is.
