#9686 closed bug (fixed)

"vfork: Invalid Argument" while executing processes that involve large amounts of fork/exec

Reported by: anevilyak Owned by: bonefish
Priority: high Milestone: R1
Component: System/Kernel Version: R1/Development
Keywords: ASLR PAE Cc:
Blocked By: Blocking: #9752
Has a Patch: no Platform: All

Description

Since the ASLR changes, attempting a jam -qj8 build of Haiku under Haiku itself frequently fails with the above error message. Rerunning the command works for a while longer, then eventually fails again the same way. Nothing of interest shows up in syslog though, and I've been unable to reproduce it while running with strace so I assume a race of some form is involved. Hardware here is a quad core i7 w/ hyperthreading and 8GB of RAM, ergo PAE is active.

I have a real problem reproducing that error (only one out of several builds failed). Hopefully fixed in hrev45550. Please confirm.

Replying to pdziepak:

Unfortunately the problem is still here on hrev45550. Clean build of haiku sources from scratch on i7 observes this issue 3 times. :-(

Since the ASLR changes, mmap will map over existing areas (particularly those at the top of the user address space -- commpage and thread stacks) if you request a large enough mapping. If the area insertion logic is broken, that could be the cause of both these issues.

You can reproduce this by mapping a few large anonymous areas (500MB+).

(In #9752) I also get a crash when using the server VM, though with a different error message to yours. Regardless, I suspect this is caused by #9686. You can use the client VM until that gets fixed: java -client <args>.

Thanks for this information. Hopefully, hrev45704 fixes both this bug and #9752.

Unfortunately it is still observed on hrev45711. :-(

PS: building Haiku on Haiku platform with -j 8 is the way to provoke this issue.
