?Hi, I was wondering if anyone has managed to get the preload_app and SIGUSR2 combination working well with upstart? My issue currently is that when I perform a SIGUSR2 against the master, check everything''s working and close off the old master, upstart then attempts to restart it because the original PID/binary are no longer running. What is the correct way of ha...

...t. I can reproduce this on my home redhat 7.3 system too. It appears to be a timing problem because when I do strace -F -f on it the problem goes away. Everything seems to go through normally but then it exits with an exit code of 12, I think because the child receiver process is terminated with a SIGUSR2 which is signal 12 and because the bug that was preventing exit codes from being properly reported from children has now been fixed. It's very hard to debug because it is a timing problem and because it happens after rprintf handling is already shut down in the child process. I suspected that m...

Hello, setting auth_cache_size to nonzero enables caching of authentication data. The cache hitrate may be logged by sending SIGUSR2 to dovecot/auth process. Is it possible that dovecot logs statistics on regular intervals ?

...from Unix(Solaris). rsync forks in this case; the parent process generates the filelisT while a child process does the receiving. (Something like that, at least; I guess it's for deadlock avoidance) At the end, the parent process waves farewell to the remote server, and then does a kill(..., SIGUSR2) on the child pid to tell it to exit. This signal seems to get lost, as suggested above, some moderate percentage of the time. The child process is supposedly waiting for this signal inside msleep(), which calls select() to wait in 20ms bursts. In the cases that the child manages to reach the se...
