Scenario:
Interactive use of our cluster relies on qlogin. To limit long
idle login sessions and runaway processes, resource thresholds
for interactive jobs are set for s_rt, s_vmem and s_cpu to large
values (8hrs, 10GB, 15min), with the corresponding hard limits
being set even higher. The system-wide bash_profile traps SIGXCPU
and SIGUSR1 and sends the user a warning that they are approaching
a limit.
Problem:
SIGXCPU is sent to the sshd process initiated by qlogin. This is not
trapped, causing the login session to close without warning.
Requested enhancement:
Exempt the sshd initiated by qlogin from being sent any of the "soft"
resource quota signals.
