• Product: Gentoo/Alt
• Status: RESOLVED INVALID

[Description Martin Mokrejš 2018-11-08 18:56:23 UTC]

Hi,
  it turned out in https://github.com/bcgsc/abyss/issues/263#issuecomment-437112339 that the startprefix bash is lying about 'ulimit -s'.

[mmokrejs@uv1 ~]$ /apps/gentoo/startprefix
prefix$
...
prefix$ exit
Leaving Gentoo Prefix with exit status 0
[mmokrejs@uv1 ~]$ ulimit -s
30720
[mmokrejs@uv1 ~]$ ulimit -s -S
30720
[mmokrejs@uv1 ~]$ ulimit -s -H
unlimited
[mmokrejs@uv1 ~]$

hmmm, so are the limits lost inside the Prefix, or outside?

[Comment 2 Martin Mokrejš 2018-12-06 10:48:58 UTC]

Ah, I forgot to update this. Turned out to be a kernel quick fix from RedHat ... Should not happen in never OS releases (CentOS 7).
