Different open files ulimit for same user in a script task

[Max]

Heya,

I've observed that printing the ulimit in a script task has a different outcome than with the same user via ssh. My setup is:

• An remote agent running as user "bambooagent"
• Logged in via ssh and running

  whoami
  ulimit -nHS

  gives

  bambooagent
  999888

• Running a script task with default settings

  whoami
  ulimit -nHS

  gives

  bambooagent
  4096

cat /etc/security/limits.conf

#<domain> <type> <item> <value>

#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50

#ftp - chroot /ftp
#@student - maxlogins 4

# End of file

cat /etc/pam.d/common-session

...
# and here are more per-package modules (the "Additional" block)
session required pam_unix.so
session optional pam_systemd.so
# end of pam-auth-update config
session required pam_limits.so

cat /etc/sysctl.conf

...
net.ipv4.route.flush=1
net.ipv6.route.flush=1
fs.file-max = 2097152

Including the shebang #!/bin/bash didn't help. This is strange since I would expect the global, user-wide file limits.
