Process lose its parent then consume high CPU usage ...
Hello.
In an informix context, on AIX 5.3 TL 12, we encounter this problem :
Sometimes in the day (probably when users exits from their session), a child process lose its parent (PPID is now "1") and this child is consumming lot of CPU "USER".
I tried, on different cases, "truss -p <mypid>" : sometimes (for some processus) it says "truss: 0915-023 Cannot control process #950712", sometimes (for other processus) it waits and print nothing.
I tried procstack <my pid> :
Do you have any clue of what happend ?
I think of the way users are stopping their sessions ... but I dont know how it could cause these symptoms.
The last operations were : upgrade AIX 5.3 to TL12 (before upgrading to 7) and move partition from Power 6 to Power 7.
Thank you !

This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...
