Description Aleksey Nogin 2002-03-28 05:28:23 UTC

If I debug a process using "strace -f" and the process spawns a child and waits
for it, strace would freeze. ps would show both the child and the parent in the
"T" state and if will stay that way untill kill -9.

P.S. Is this related to bug 53191?

Comment 1 Brent Fox 2002-04-09 15:28:54 UTC

This looks very similar to bug #62591

Comment 2 Aleksey Nogin 2002-04-09 17:38:07 UTC

Yes, bug 62591 is definitely a dup of this one (judging among other things by
https://bugzilla.redhat.com/bugzilla/showattachment.cgi?attach_id=51924 ending
with a child's _exit).

Comment 3 Aleksey Nogin 2002-04-09 17:40:26 UTC

Still seeing it with
strace-4.4-3
glibc-2.2.5-30
kernel-2.4.18-0.13
