View all threadsCore Dump in CommonAPI DBus
Hello,
We found a core dump in CommonAPI D-bus wrapper. This issue has been occurring sporadically hence could not get any more logs. From the trace logs we could not determine the root cause behind this.
Please help us determine the root cause. Or provide information if this kind of issue has been reported before and solution if any.
Following are the details.
Version Information :
CommonAPI 3.1.12
CommonApi Dbus 3.1.12
Dbus 3.19.7
Back Trace :
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
