Description Denys Fedoryshchenko 2011-05-18 21:19:35 UTC

Hi, not sure it is a bug, even maybe cosmetic one, but worth to report.
If it is not a bug, just close it.
Thanks for your great software!

tail: memory exhausted

Comment 1 Denys Vlasenko 2011-05-19 22:32:38 UTC

Fixed in git by commit 9e933d9bfc7f52a7d8bc61805f70e3039b30216f. Will be in 1.19.x

(BTW, "tail: memory exhausted" happens only if your architecture is too stupid to not "allocate" 1G of non-existing pages, if needed. NOMUU? Alternatively, you may run in no-overcommit mode...)

Normal x86, glibc.
Latest kernel, almost latest glibc (at least recents one)
