[Eisfair] [E1]: shell level (1000) too high, resetting to 1

[Rolf Bensch]

Da sind die Fehlermeldungen wieder. root meldet um 00:12, 00:15, 00:18 
und 00:21 Uhr mit Subject "Output from your job 396038" und text "shell 
level too high". Danach keine Meldungen mehr.

Die Job-IDs sind unterschiedlich die Anzahl "shell level.." auch.

n36l # grep 396038 /var/log/*.*
/var/log/certs-update-crl.log:Jan 24 00:18:03 n36l 
certs-update-crl[2073]: - job '396038' (2019-01-23 00:21->2019-01-24 
00:21) created.

In /var/log/messages finde ich zeitgleich:

for user root by (uid=1)

Wie hängt das zusammen?
