As reported by nyan86 on Discord:

i think there is some problem in the desc.
If you make a text request e.q with IS_SERVER_UP there is a strange return:
b'\xfd\x01\xff\xfd\xab5[FQ\x00\x00\x00\x00\x00\x00

Looks like some kind of buffer overflow or something like that?
Traced the calls back to RawPacket but dont know what might cause the issue.
In addition if you do that quite frequently an error appears in the logs:
[2024-06-20 16:27:37.962] [error] [desc.cpp:57] DESC libevent error, handle: 60
