We have recently started experiencing suite tasks failing with a
database is locked while polling via
cylc suite-state another suites database. Cylc version is 7.7.2.
Specifically the issue is from ensemble post-processing suites polling the ‘parent’ forecast suite. The issue seems worse if the suite server VM is more heavily loaded.
Is this a known issue? Is there anything that can be done (a[art from upgrading these suite to 7.8.x and using external triggers)
Any assistance is appreciated.
