All of a sudden I started getting this error at mtproxy startup:

mtproto-proxy: common/pid.c:42: init_common_PID: Assertion `!(p & 0xffff0000)' failed.
[pid 215403] [time 1591001426]

Guys, in modern Linux environment PID can be higher than 65535. This is the default on Oracle Cloud instance:

$ sysctl kernel.pid_max
kernel.pid_max = 4194304

Same on Google Cloud.
