[Linphone-users] ERROR: Failed to connect pipe: Result too large

[Wedel, Jan]

Hi,

I'm randomly experiencing the following Error message:

ERROR: Failed to connect pipe: Result too large

This has been already reported in 2010 on the mailing list, however the reply 
from Simon Morlat (Thu, 09 Sep 2010 21:54:12 +0200)  was:
>> I have absolutely no idea. Is it on linux ?

Unfortunately, the questioner never replied.

I can answer that for our scenario: 
This problem occurs on Windows, specifically on Windows Server 2008. Connecting 
to that same SIP GW on Linux doesn't bring up this issue.

As already said, this error occurs only from time to time. But since were using 
it for machine notification (i.e. not real audio is transmitted, just ringing 
and hanging up), every erroneous call is in fact a problem for us.

What we are doing is:
- Checking if the linphoned is running, if not call "linphonecsh init" and 
waiting 3s
- Issuing "linphonecsh register --username <username> --password <password> 
--host <gateway>"
- Starting the call with "linphonecsh dial <number>"
- waiting some x seconds (40s)
- Terminating the call with "linphonecsh generic "terminate" "

The output is in case of the error:
  WARNING: no real random source present!
  WARNING: no real random source present!
  ERROR: Failed to connect pipe: Result too large
  No active calls
  WARNING: no real random source present!

And in case of a working call:
  WARNING: no real random source present!
  Establishing call id to <sip: <number>@<gateway>>, assigned id 6
  Call 6 to <number>@<gateway>in progress.
  WARNING: no real random source present!
  No active calls
  WARNING: no real random source present!

Is there any obvious problem with that? 
Is it e.g. necessary to call init everytime or to stop the deamon after every 
call?

And by the way, is there any way to suppress this warning:
WARNING: no real random source present!

Thanks a lot,

//Jan
