2.39. PIDcheck *global*
If non-zero, enables a check of running Interchange processes during the housekeeping routine. If a process has been running (or is hung) for longer than PIDcheck seconds then a kill -9 will be issued and the server count decremented. During the housekeeping routine, the number of servers checked by MaxServers will be recounted based on PID files.
Default is 0, disabling the check.
If you have long-running database builds, this needs to be disabled. Set it to a high value (perhaps 600, for 10 minutes), or use the offline script.
