I think i found a "workaround" for this problem. After set the trace_syslog to 5 i also changed this: # # Child process is restarted after handling this many connections. # MAXCONNECTS = 100 # # Child process will restart after this many connection errors. # MAX_ERRORS = 5 After that, no more hangs.. Decrease MAXCONNECTS seems to help. I hope this could be useful for who is exeperiencing this problem.
