I’m in need of some ideas on how to debug a QNX 6.3.0 system. The system will occasionally (intermittent, I can’t duplicate it on demand) appear to lockup; what I mean is it will not accept network connections - none of the normal services like ftp respond and it will no longer answer to a ping. The photon session doesn’t respond to any actions - the mouse no longer moves and all keyboard actions apparently have no effect. Does anyone have a idea on how I can tell what processes are running and possibly taking up all the processors time, during the apparent lockup? I’m assuming there is a process that is a fairly high priority and it is consuming all available resources and it not releasing them.
The system that we are running on is a fairly typical PC, nothing too special hardware wise, SCSI controller, Intel P3…
Thanks for any help or ideas,
