Dear Maintainer,
I tried to have a look at this issue. I got this also on amd64 [2].
It looks like this is related to aeolus requesting its
memory never getting swapped out. [1]
Without this line a process does not give this fault.
But there is a "max locked memory" of 65536 kbytes
in place (ulimit -a).
Unfortunately aeolus need this limit at least raised
to 85000 kbytes.
I tested to raise this limit by doing following changes:
/etc/security/limits.conf
* - memlock 100000
/etc/pam.d/common-session
session required pam_limits.so
Kind regards,
Bernhard
