Another crash today after less than 24h uptime. This time I attached python electrumx_server process to gdb debugger.

Dmesg didn't register anything as error has been caught by gdb as I understand. But probably I did something wrong with gdb as I got "Couldn't get registers: No such process." and no real debug outputs. I will be happy to hear how can I run gdb with electrumx.

And another one:

While electrumx crashes very often, bitcoind continues to run and uptime is 25 days.

Another one after 7 days uptime: [Wed Oct 7 07:17:59 2020] electrumx_serve[3848664]: segfault at 0 ip 0000000000000000 sp 00007ffd540d52c8 error 14 in python3.7[400000+21000]

Bitcoind uptime 32 days.
