A coworker opened a ticket for me to examine why a server went down. He then rebooted the server and left me five lines of logs, with the most interesting entry:cron[1187]: (CRON) error (can't fork)There is nothing in /etc/security/limits.conf, so my guess is that we hit pid_max (32768), but I would like to know for sure. Is there any log file that would have more evidence pointing to how many processes are in use, or some other trend to confirm my hypothesis, after a reboot?
Retroactively see if we hit pid_max
process;fork
