Set FCGIDZombieScanInterval, which defaults to 3 seconds, down to 1. But
note that it may not scan for zombies every second because of this <=
comparison:
/* Should I check zombie processes in idle list now? */
if (procmgr_must_exit()
|| apr_time_sec(now) - apr_time_sec(lastzombiescan) <=
sconf->zombie_scan_interval)
return;
Maybe set it to zero to mean 1 second ;) It doesn't currently complain
about a setting of 0.
(It would be nice not to have to scan for zombies at a set interval. The
process manager could be awakened when a subprocess exits, at least on
Unix.)
