Description

The GOC saw os.fork() fail because no more memory could be allocated.
If this happens, we should catch the OSError and do something.
(It would be good to figure out why it happened, too.)

History

#1 Updated by Igor Sfiligoi about 6 years ago

os.fork() failure may not necessarily be fatal.

We should be able to recover, especially if it is a group fork, since we can have an arbitrary number of them.

Reducing the max number automatically on failure may also be a good idea.

#2 Updated by Burt Holzman about 6 years ago

Parag had the same comment, but I think fork failing should be fatal -- we really can't do useful work at that point and the machine
is nearly out of memory.

Remember that the factory will restart the entryGroup when it exits, so the factory will keep chugging along. And restarting
the entryGroup should defragment the memory too (if that's what causes the PSS to increase over time).
