      2020-05-26 08:15:46 GMT WARNING [0x7f461d2af700:13241]: process_dead(): unable to verify liveness of rw lock process 31376 (error 1)

      reproduction
      Not found one yet.

      analysis
      The error and looking at the code shows that this is an EPERM / permissions issue. In the observed case they are using prefork which uses many times more processes (up to 150 rather than a small number like 5 or 20). This may make it easier for another process to reuse an old process id.
