(1) I can not build it WITH_DEBUG, looks like this setting is broken, as many internal libraries are linked dynamically and mot installed. I see complains about this problem on some forums for Linux, looks like it is upstream problem. (2) Exceptions without symbols looks like this: 2021-12-31 11:18:00.339 [P2P8] INFO stacktrace src/common/stack_trace.cpp:134 Exception: boost::wrapexcept<boost::bad_weak_ptr> 2021-12-31 11:18:00.339

src/common/stack_trace.cpp:149 Failed to find the next frame When monerod starts synchronization, it works Ok for hour or so, but later these exceptions occur from time to time and after about 3 hours there are only these exceptions in the log, back-to-back. When such exception is printed out, monerod consume 100% of one core and stack trace is printed out one line per second (!). Synchronization effectively stops. Exception like this is mentioned in https://github.com/monero-project/monero/issues/6473 which is closed as fixed / workarounded. -- // Lev Serebryakov
