I’ve running a multisite checkMK (1.6.0p11-cee) installation with 4.5k host and 150k checks.
Over all there are 20 sites up and running, which is needed because of network topology
for more and more queries in WATO we run in timeout:
Internal error: Your request timed out after 110 seconds. This issue may be related to a local configuration problem or a request which works with a too large number of objects. But if you think this issue is a bug, please send a crash report.
mostly when we do activation of changes ;-(
