BNC crash due to not catch exception

[droma@…]

I'm sorry, this is the first time for me reporting a BNC bug and I didn't found any procedure of how and where to do it. Please let me know if I'm reporting it at the wrong place or if you need any more information.

Recently our BNC (Bnc2.11.1-CentOS6-64bit-static) crashed with the following output message:

RTCM2_23::extract: P.nDataWords()>=1
RTCM2_23::extract: P.nDataWords()>=1
RTCM2_23::extract: P.nDataWords()>=1
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

The bnc_update.log doesn't show any information related to the error.

Would it be possible, to give me access to the data stream, which is providing such error message?
Thanks in advance, Andrea.

I really don't know which is the one causing the error, we're feeding form around 150 different streams. Is there any way I could find it? I could also provide you with the log and the different mountpoints if it's any use for you, but since I will remove the user and password I don't know if you will have access to them.

The data stream providing the error message is one using RTCM format version 2.3.
I hope, you have not 150 data streams using RTCM version 2.* ;)

It would be helpfull to have access to the RTCM version 2.* data streams in order to reproduce the error. Otherwise, it's difficult to find the reason for the crash.
We would use your provided user name and password data for test purposes only.
Best regards, Andrea.

Dear Andrea,

you're right only four stations are in RTCM_2.3 format:

['www.euref-ip.net:2101/VIGO0', 'www.euref-ip.net:2101/ROVE0', 'www.euref-ip.net:2101/ALME0', '200.3.123.65:2101/RUFI0']

In case you don't have access to some of them, please let me know and I will ask our group manager if I'm allowed to share with you the user access information.

Be advised that BNC was running about two weeks before it crashed.

Regards,
David

Hmm, strange, I took a look at the caster ​http://200.3.123.65:2101/ and the station RUFI0 seems not to be listed there. When we started BNC it was there for sure. Could this be related to the problem?

Dear David,

thanks for your hints and the list of mount points. www.euref-ip.net is our own caster so we have access to its streams ;)

Furthermore, it is no problem for BNC, to handle disappearing mount points.

I will setup a long term test using a lot of RTCM2 streams in order to try to find the reason for the crash.

In case of success, the findings will flow in BNC version 2.12 that is under development and shall be available soon.

Thanks again and best regards,
Andrea
