I am working on tango device server part, as I start tango DS it is automatically being killed after sometime. I have attached the screen-shot of jive & gdb logs. From the GDB logs, I can see tango DS process is getting "SIGABRT" signal and because of that it is being killed. I am not getting why it receives SIGABRT signal. Anyone has any idea why it is getting SIGABRT signal with message : Assertion failed: erased == 1 (mtrie.cpp:292) ???

Hi, It would be interesting to get more details. What version of the C++ tango library are you using? What version of ZMQ are you using? Can you reproduce this easily with a simple C++ device server? If yes, can you please share the source code of the simple device server and give instructions on how to reproduce the problem? I found these issues reported on zmq github repo which look similar to your problem: https://github.com/zeromq/libzmq/issues/2942 https://github.com/zeromq/libzmq/issues/2252 Cheers, Reynald

When looking at https://github.com/zeromq/libzmq/issues/2942, here is the description added in libzmq README when it has been fixed (in ZMQ 4.2.4):* Fixed #2942 - ZMQ_PUB crash when due to high volume of subscribe and Do you have a high volume of subscribe and unsubscribe messages coming to your device server?

Hi Reynald , thanks for the prompt reply.What version of the C++ tango library are you using? What version of ZMQ are you using?We are using 9.2.2 version of C++ tango library and 4.0.7 for ZMQ Can you reproduce this easily with a simple C++ device server?I will try to reproduce this with a simple device server program. Do you have a high volume of subscribe and un-subscribe messages coming to your device server?Approximately 5 - 7 clients subscribe to a particular attribute, however, the attribute value change is approximately 2 messages/sec.

Further findings after updating ZMQ_v4.2.5: Changes in Taurus labels values are not updated however the attributes with static values are visible on Taurus label. Taurus version: 3.7.0 Please find attached POC screens with different ZMQ version
